  • The enemy sprites in the Arena now match their versions in game.
  • The entire Arena Map has been overhauled to match the world map displayed on the title screen. Because of this enemy locations have been moved slightly. Some can now be accessed via entering a portal to a different map (The Demon Zone Forest, The Mansion and the Pyramid specifically)
  • The entrance and exit location on the Arena map are now matched to what zone you entered from.

The “Rapid Stance” makes Dominic much better at avoiding attacks, but those that hit do a lot more damage.

 Gotta be the best game (in my opinion) on the website.

Let me explain, this game has "bad endings" in which you're transformed and game over. Massive advantage over other games if you're looking for a quickie, but NOT JUST THAT!

 This game is like a proper Ero.. No, a proper game that happened to have sexual undertones. No joke. Massive interconnected storyline, with a somewhat openworld. Not to mention the combat is decent!

I loved this game, It's almost perfect. It has endings to give you that lust-fullfilling experience and not drag it out too long ... that your hard rock became soft sponge. But this game also has depth. It's not as repetitive as most games here, and the combat's quite balanced.


 I've replayed this game for over 4-5 times at this point, and it boggles my mind how this game hasn't gotten 1000 likes. I've searched for countless games like this, which has the perfect balance of eroticism, and gameplay.... the nearest thing that I've found; is monster ts game 3 (even then, that can't even be compared to Monline's sheer size).


 I don't have any problems, only a few nit-picks, and that's only based on my preferences. Overall, this game is a masterpiece. So, if you haven't, just check it out man, it got it all. From hero journey-to-fetish fulfulling eroge.


 Although the artworks are "borrowed", Author is a man of culture in choosing the art. And the "bad endings" could be repetitive on paper, but the endings so far, are quite... HOT.


 Just check it out, it's great.

One of my favorite games of the style. It's fun, even if it didn't have the porn part (that is also good, although mostly bad endings).

The good part is that it's 100% free, and the bad part it's the extremely big time between updates, but maybe these two things are related.

The art is also not original, but it's a common thing here. At least they are mostly well chosen.

Characters are not too complex, but they work well, just like the story. And I don't understand why it's so hard to cheat, but at least there is the classical "enter cheat codes".

And the fact that I can equiip 2 one handed swords without being the biggest shit possible ingame is awesome, even though my favs ones are only on late game. I know that it's a small detail, but like it, but it's a rare thing in games.

Major TF Theme: Human Male to Monster Girl (MtF)


Although I'm not a fan of MtF TFs, I think this game is still a great game to try. It's massive, and there are countless (bad) endings. Also, the developer of this game put a lot of efforts in designing different characters and dialogues as seen in numerous reactions and interactions.

This is the first game that I ever played on this site and it is still one of if not my favorite. It has a great story, its exciting and fun. You can clearly feel the time and effort the creator has put in this game and I would Highly recomend a playthrough. You ceartanly wil not regret it

This is a great game and as many others have said it's one of the best on this site. I love the game and its a weirdly satisfying game to play. I played it for the first time and tried to find as many bad endings as possible while still progressing towards the goal. As some others have said there is a bunch of content and it definitely doesn't feel as linear as some other games of the same caliber. 


The one big thing I have with this game is that it's on the RPG Maker system. This is not something on the creators end so don't think I'm saying anything on that end. In my past experiences the RPG Maker system is just way to finicky. Its a great system and lots of people have made great games on it but I seem to keep finding bugs and crashes on games using this system. Just want to say again - this is not on the creators end, its more of the system. I've used the RPG Maker system before and there are some weird weird bugs.


But anyway this game is great and everyone should try it but I feel like people should start leaning away from the RPG Maker system
