Yorna MGS
by yeehaw games

A young mage from a noble family arrives at a distant castle to find it ruined and her sister missing. Will she able to recover lost monster girls and restore the peace with their power? What price will she have to pay?

Ada, the female protagonist, is a prodigal mage with the ability to use monster girl's power as her own. Combine them to create your own play style from a powerful battle-mage to a delicate temptress. Will you overcome your enemies through force or make them into your toys? It's up to you!


Info for v0.1 -> v0.1.5 update


Version 0.1.5 brings the usual content pack: a few new zones with a puzzle, secondary quests, a psycho-parrot pet and 3 core scenes each with 2 variations - normal and lewd. 2 of such scenes are the standard boss and monster scenes and the last one is special. It's a repeatable modular scene. More on this in the features section.

I also updated the “Special Controls” help text both on the Patreon and inside game packages. Now it should be easier to navigate and use.


Interactive non-linear scenes

I made an experiment with H scenes to test out modular and repeatable scene structure for the future. You can check it after getting a maid dress from the dressmaker and accepting baron's offer for work.

This system allows players to try out a new approach with shorter, non-linear H scenes. During the scene, players will have several options to respond and act differently. Depending on the client's character and Ada's sex skills, players will get various rewards - from gold to items.

This is the first step of implementing such scenes with just one client. Later releases will have more poses and sex types, plus more characters and interactive options. Also, I plan to add more frames/pictures to all scenes later, after Yorna achieves the first Patreon goal. As it all depends on player interest, I'll be glad to receive feedback from you.

Shortened Scenes option 

From the 0.1.5 version onwards Yorna supports an additional option for players who want to shorten the length of H scenes in the game. It's available through the main options menu and defaults to "Full" setting. Both "Full" and "Short" versions use the same graphics base and differ only in the text length. You can switch between versions any time you like.

This setting affects both gallery and "on-map" H scenes. All scenes support this feature.

I appreciate your feedback about the feature. Contact me with your thoughts via mail or personal messages.  

Upgrading your castle

Version 0.1.5 brings options to repair your castle and add additional functions to it. To access the upgrade menu, talk to the Adviser Arthur just outside the castle. Minor upgrades are available from your castle's workshop once you've completed the first stage of repair.

At this time, minor features include Ada's personal room with a pet and a herb garden for your alchemical needs. This feature will get more options in the later updates.

Improvements and fixes

Added a cursor image to show the active digit during code input for gallery unlock.

Gallery mode now listens for the Escape key and allows to jump 1 level up in the menu tree up to the main game menu.

Fixed Ada's sex skills info. Now all of them show in proper places in the table.

Crafting materials requirements now follow a clearer notation: materials required - space - slash - space materials in your backpack.

Target window for using food or potions lost the default border setting and is transparent now.

Cleared the cursor in the loot window. It didn't serve a purpose there because there's no choice in the reward collection. You get them all.

Fixed combat background randomization. Now each of three battle backs has exactly 33.3% chance to appear. 

Fixed battle sprites for bosses during in-combat dialogues. They don’t overlap with combat info bar anymore.

Fixed a visual bug with a botched tree in Nymph's forest entrance section.

Updated the Hall of Fame map with a few new names. Also, you can exit the credits section by hitting the Escape key without waiting for the roll-over.

Added short tracks for pianos inside baron's mansion. Yeah, classic music!

Fixed a few minor typos in some descriptions.

Marked logo – loading screen as such to avoid possible confusion during Yorna’s loading.


Info for version v0.1.5 -> v0.2.0


Graphic and scenes

v0.2.0 has 2 new scenes in lewd and normal variations – 4 new unlocks for the gallery. The “maid job” recursive scenes receive 13 new frames with new graphics and 2 new clients with their own character and gifts for the job well done. New frames are focused on Ada working with her hand and happy endings.

As the result, recursive scenes has more variety now. I will add lewd sound to these scenes during the next update – didn’t have the time in this dev cycle.

Monster girls receive their own sprites and mini-cutscenes in the castle. Calista the lamia will receive her unique sprite in the next update and I will try to move from generic stuff towards more specific and original graphics. Yorna v0.2.0 has 2 custscenes: 1 for Leary and another one for Gabby.

You can try out 2 new dresses. One can be crafted after updating you castle to lvl 1, which you could do in the v0.1.5. Check Diana’s shop afterward. The lamia boss has the other one.

Your castle and improvements

Players can upgrade their default “Firepuff” magic skill to a more powerful “Fireblast” in the luxurious Ada’s room. Check the bookshelves on the left.

You can upgrade your garden with a batch of red herbs for alchemy and other crafting needs. Also, I added a well inside the herb garden to gather water. All water gathering yields twice the amount to speed up the gathering process.

Castle receives a default “kitchen/mess hall” zone where you can buy food with a discount. Plus, you can check how well Gabby is behaving while you are gone. After all, the girl has her needs…

Arthur no longer gives the introductory cutscene if the player visited Ada’s room on their own before triggering it.

Crafting and alchemy

Sand tribe’s town offers a book with advanced alchemy recipes. Buying it unlocks new types of more effective potions.

Added materials to monster’s drop list to make crafting easier and more appealing. Reduced crafting cost for some weapons to make them available earlier.

Interface and GUI

Added gold window to the main “on-map” menu. Now you can check you money by hitting the escape anywhere.

Moved status bar under HP and MP bars so players could clearly see the debuff or buff icons.

Removed confirmation on healing items in-combat because Ada is the only correct target for them.

Increased the size of gallery preview pictures so you can clearly see the details. The screen holds 4x3 pictures at the current configuration.

Added scrolling to the gallery mode. To view all the scenes (14) you need to scroll down by pressing the arrow with the mouse pointer or tapping down on the keyboard.

Renamed “Blowjob” to “Oral” as Ada will get opportunities to dive between ladies’ legs too.

Balance & enemies

Placed some monsters further away from entry points so players could away combat if they decide to do so.

Rebalanced the oni so you can beat her easier. She was pretty tough in the v0.1.5 and players had problems with her.

Adjusted skeleton’s movements speed to the usual “aggressive standard”. They were faster than intended.

Losing to monster and bosses now yields less SP. I increased SP for wins to counter this change.

Other changes and improvements

Deleted debug tiles which slipped in during the previous dev cycle. No more cheating :P

Fixed mountain tiles on the global map. Now they are stick together correctly.

Fixed ignored sprite hide command for Ada during one of the dialogues with Arthur.

Fixed some lewd sounds which had a strange panning to the right. Must be a misconfig on my part.

Fixed a bug with the gallery not unlocking the second type of the scene for a specific monster if players already got one type of scene unlocked and had “Skip” as their watched scenes option. Now it works with all the options.

Fixed a bug which blocked the alchemy table in Ada’s room. Now you can brew at home too!

Fixed visual jitter if players attempted to use a pedestal in oni’s puzzle without orbs in their inventory.

Fixed some typos and missing actor tags in dialogs.


Info for v0.2 -> v0.2.5 update


Scenes and Art

V0.2.5 has 2 new base scenes, each with 2 variations - normal and slutty.

The mansion got a new type of interactive scene - coach adventures with some backside exploring. The scene has all the 3 clients from the start and supports gallery activation. Similar to the first, blowjob scene, it will receive extra frames and branches in the next Yorna update, bringing it to the full intended scale. Also, I plan to do a half-clothed version in v0.3.0 if the time will permit it.

Just as previous feedback poll suggested, I added H sounds to all interactive maid scenes, both new and old. This change includes all clients and variations inside the scene.

The second base scene is centered on the big cat that you will find in the new forest zone along the plot line. ”The Big Fluff” monster girl is also present but, at this update, limited to plot story involvement, cutscenes and some mind-reading tricks. Also, teasing and fluff domination :p

Main Features

Yorna received the base logic for enchanting items and you can test it out with the sword part you’ve been collecting through your journey. v0.2.5 has the third and last piece so you can assemble the blade and tune it to your preferred play style. To use this feature, you’ll need to restore your castle after gaining the trust of a certain furball.

There are other improvements you can do - like repairing the shortcut bridge to your castle. Visit the lumberjack village for this opportunity.

I will expand the enchanting system to more items in the upcoming updates since the idea of giving more slots for equipment weren‘t solved in a satisfactory way. Every solution had its own drawbacks, so I decided to do this kind of sidestep. So far I see no penalties for using it and plan to support it all the way to Yorna’s final release.

v0.2.5 got the biggest pack of cutscenes and monster girl sprites out of all previous ones. All of them received synchronization of big on-screen sprites and portraits inside the text block. This includes all the previous monster girl cutscenes too.

I plan to use such cutscenes to add more monster girl interaction after their initial capture and some choices with buff or item rewards in the future.

Also, I finished all the monster girls sprites and plan to avoid using general ”flying ball” as an enemy sprite. Hopefully, this will add a bit of immersion to the game.

Small improvements and fixes:

Adjusted the gold line in the after-battle loot window so it doesn‘t climb higher than intended.

Fixed a single castle tile which was ignoring local -> global map size conversion. No more pygmy Ada :p

Re-marked craftable sword pieces as key items to avoid showing them in the regular inventory and confusing players.

Changed active piano sounds in the mansion.

Reduced costs for Sand Town smithy – the novice staff was too expensive.

Fixed a rare looped start for the interactive maid job scenes. It sometimes happened right after finishing one scene and the second one started without getting the money from Jack.

Added a mention of a local alchemist during Deadroot monologue to help players locate the interested person.

Fixed alchemist quest so she no longer asks players to get some Deadroot after they already gave some to her.

Changed grass graphics inside the Grey encampment - the edge is no longer looking like it’s close to a chasm.

Fixed some typos, missing dialogue tags and passable map geometry.


Info for v0.2.5 -> v0.3 update


Due to the previous goal and the new artist I prepared 3 scenes + extra frames for the sofa scene in the mansion. News H events feature moth, raiju and Baron Sebastian in a special scene after getting a high score with any of the clients.

I added a clothed variation to the sofa scene and made different frames for outer and inner finishes. 10 new frames in total for this scene. Special event with the baron is a one-time scene so getting a normal variation will unlock the lewd one too and vice versa.

I hope the next month will involve less "behind the scenes" changes and more work done. Yet it's understandable that newcomers require some time to settle in. Hopefully, the next month artist can step back a bit and update an existing scene for better quality. Something like we already did with mansion's scenes.

We'll see how it'll go.

Performance and tech updates

I migrated Yorna to RPG Maker v1.6.1 and Kadokawa fixed most of the problems in a year. I also tweaked the plugins and pruned less useful of them. Both garbage collector and pixi graphical engine received some love too.

The results are quite nice - resource consumption went down x1.8-x2 compared to 1.5.2. Yes, there is a gap in results due to the testing methods I used – I’m pretty sure no one will fast-forward different scenes 50 times in a row. Right?

All features and saves are compatible so you don't have to worry about starting a new game for Yorna v0.3. There are some things to polish but I’m happy with the results as is. The next big tech thing will be MacOS investigation.

I shortened the SP calculating delay after battles as some players thought their game froze. The logical functions are still the same.

Features and interface

Players wanted to see the names for H scenes in the gallery, even locked ones. I implemented this feature so you can get the hint how to get your locked events.

Deafeted monster girls will offer a small stat increase after you bring them to the castle. This is still a work in progress and you can expect more such interactions. Check your castle - these events are among the new monster girl cutscenes pack.

Now you can buy herbal tea to counter Ada's lewdness if it gets too high for your liking. You can't get her to a completely pure state though and remember - using the tea will make lewd skill training harder in the future.

Added dynamic shadows as a test feature. This means they will properly darken all objects under them, not just floor. Default RPG Maker's shadows are boxy and meh at best so I experimented a bit. If all goes well all shadows will be swapped to the advanced variation.

Minor updates and fixes

Fixed a flicker with calculating numbers inside the combat screen. Now there's nothing appearing under Ada's HP and MP bars during hit animations.

Arranged combat sprites closer to the center of the screen for better composition.

Increased healing skills cast speed to help players with "Oh crap" situations.

Changed Jack's dialog so he could appropriately comment on Ada's lewd level during their first scene.

Blocked the function to press and hold action button on permanent interactive vents like wells. Plugins didn't like such interactions.

Fixed a small cliff inside the desert zone. Previously players could climb it even without vines.

Allowed to eat "lizard-on-a-stick" item both during combat and map exploration as it was intended. Yummy! (Careful with food poisoning tho)

Fixed gnoll's battle skill description during the animation.

Fixed jinko's (tiger) scene results. Now it properly unlocks her scenes according to Ada's lewd level and checks if the player wants to skip the second playthrough of her scene.

Fixed Diana's store not offering all the intended dresses after upgrading the castle to the last stage.

The usual typo and dialogue tag fixing


Info for v0.3 -> v0.3.5  update


H Scenes and art

You can get new 4 new scenes. 2 base events, both of them with lewd and normal variations. We also added the first batch of new frames to the moth scene. You don’t need to re-unlock it, just you the gallery if you had it before the update. As I mentioned earlier scenes will get some love in the future updates.

I postponed the third scene to November and it will be the third variation of the mansion “Maid Job” H event with Ada being… on top of things. More on this in the upcoming developer plans for November -> December.

Mechanics and gameplay

Version 0.3.5 has 2 new dresses for Ada: one for beating up the boss and the second one is available in Diana’s shop. Craftable dress features new mechanic – stealth. Using the active skill of this dress, you can ignore common enemies, as they can’t initiate the combat with Ada even if they catch her. Use it for resource gathering and puzzle solving.

I saw the parity inside the cutscenes poll and will weight my ideas accordingly for the upcoming releases. 0.3.5 still has a pretty lighthearted mood for most of the cutscenes. This doesn’t mean there won’t be any cute or funny events in the future though.

Your castle’s lab is finally up and running! For now, you can upgrade a bunch of trinkets but with time you’ll get options with weapons and armor too. Talk with the lab staff to access the upgrade menu and prepare to spend your cash together with the new material – focus crystals. To avoid various strange scenarios players should un-equip the item they want to strengthen. Otherwise, it won’t appear in the menu.

A new type of game package

Testing showed I can use online platforms to deploy Yorna for playing in browsers. Controls are the same, including mouse options and the game runs smoothly performance-wise. The problem for such deployment is underlying web server - sometimes Yorna’s logic breaks completely while other web servers allow achieving performance close to a local client.

This means I will try several platforms for distributing the public version of Yorna and see how it‘ll go. If everything will be fine players will get another option to play the game without even downloading it. Yet no promises - it all depends on the platform and its staff. 

Small fixes and improvements

Added a switch to bring the desert puzzle back to its original state. It’s on the northern wall of the room.

Switched the “glow” effect material nodes have from white to red for the winter regions to make them more noticeable. Crystal caverns use sparks instead. 

Healing via the statue shrine will not force players to confirm the info message. Now you can use the statue and immediately move even with animations still playing.

Fixed Sebastian’s special scene in the mansion. Now it correctly works for both lewd and normal variants without allowing players to trigger it twice.

Re-linked the requirements for getting into Oni’s sand caves to finishing the first of Arthur’s quests – get him the Mothercare plant instead of overall clear. Some players got confused why their castle never progressed – that’s why.

Ada and enemy skill changes. Previously mage path with spamming firepuff/fireblasts had too much value for 1 mana point.

Added a note about saving before checking out the gallery if players used boss unlockable items after defeating them.

Leary, Gabby and Calista no longer disappear before their cutscenes end so Ada doesn’t talk with an empty space anymore.

Arthur will not only check if Ada has needed materials during the first update but also take them after player’s confirmation.

Added a note about the mountains in the East to the help message when Ada talks about Oni’s caves.

Spell blade now actually uses zoom-zoom sound during the attack – just as its description says.

The game is a good start, though you should know this is a lot like Melty's Quest that you can find on steam.

I hope you can make it as good as that game.

Really great start!


Awesome game loop:
Collect outfit -> Wear outfit -> See pretty girl in outfit -> Gain SP for outfit via combat or sex -> Learn ability from outfit up max SP -> Collect new outfit.


There's a also a scavenge and craft system as well as monster girl collecting.


Only downside is that as of version 0.1.5, there's only one monster girl and two outfits.


Looking forward to more content! =D

The game crashes when you try to save when playing the mac version, and I have no idea if the other versions also have the same issue. It's quite a major bug so I hope it gets fixed soon.
