The Essence of Gender
by ugre101


The Essence of Gender is an 18+ game where the core game mechanic revolves around taking and losing essence of masculinity and femininity. 
I plan to add a lot more features and because I code the engine myself I will be able to add any feature I can code in JavaScript/HTML5.


The game is made in HTML5 so a up to date modern browser in needed for it to run correctly.

Firefox or Chrome is recommened.

The game is a (text?) rpg with support to add a image pack.

I am new to writing as I am more of a coder guy, so until I get more experienced text/dialog will be lacking.


The game is still early development so there is much to be done but getting opinions will help the development a lot.
Opinions on design(css) and balance are greatly appreciated. 
And please report any bug you encounter (with info from console if there is any).


Github for source code:



I'm really happy for the suggestions & feedback, if possible post a copy of your feedback/suggestions in the Discussion Thread so that I can comment on it for clarification etc. 


Magic world.

V0.288 more bug fixing

  • Some style changes.

V0.286 more bug fixing

Release note:

  • More changes to styling.
  • Changed a lot input buttons to buttons
  • Remade backside of dungeon.
  • Moved vore engine to follow time system instead of main loop, mainly because I want sleeping to affect digestion.
  • Some other bug fixing.

Smaller update
Release note:
  • Improved syntax and implemented checks to stop crashing.
  • Dorm and voremenu changed to javascript.
  • Trying changes to movement and finally multi key movement works.
  • Played around trying to improve css. 

Bugfix for:

  • Essence drain of femi
  • Enemies spawning without chest
  • Flat chest becoming an flat cup chest

Release Notes:

  • Testing new way to handle auto essence, it's basically manual essence but auto, so essence is now consumed when organs grow. This also means that when you siphon essence you first siphon their essence and then you recycle their organs for more essence.
  • Started improving minimap with images and icons.
  • Splitted what is paused in menus, building, home, etc.. Probably missed somewhere, the goal is to make it so game only really paused when in combat. 
  • Improved combat text log so it saves each turn, this one of first steps to be able to have combat with more participants than just player and enemy. Also made combat turn based but that shouldn't make any difference right now.
  • Fixed bugs and improved syntax, game should be more stable and less prone to mutate variables.
  •  Improved handling of custom image pack with "yllarius" mode, to use it click on "img pack" in option until it appears.

On the new image pack system the idea is that you should only need to insert images to right folder instead of having to name each image, then you click on the ClickAfterAddingImages.exe and my python script reads the folders and write a javascript const with arrays. It most likely need more work esspaality tutorial on how it's works, but I really like it so far and think it can become a really nice tool.

This game is surprisingly enjoyable, even in this very early form. Having looked at the Javascript source code, I can tell a lot of work went into this game, even though it doesn't show on the surface. There's thousands of lines of source code. Like most TFGamesSite games, this game is incomplete, but it's certainly worth a look.

Graphics: 2 (Very simple 2D pixel graphics, with no animated motion. At least it's not another pure text-only game.)

Gameplay: 6/10 (This is where the game really shines. It reminds me of Corruption of Champions combat, except without the wall of text after each action. I'd like to give it a higher score, but the game is still very early. I'd like to give it a higher score here, because this was all done by one person, but I just can't.)

Story: 1/10 (You roam across the small game world freely without any pesky story getting in your way.)

Sound: 0/10 (No music, no special effects, no sound)

The writing definitely needs work, maybe another person who'll look it over as well.


What's there is already very solid. It's no TiTS or Lilith's Throne, but it's good.

This is WOW. A very interesting game.

My first impression of it is that it is a poorly made rpg-maker-overseeing sandbox map... but that word "poor" is a result of comparing the game to an rpg maker game with a well established resouce library as the foundation. As an HTML game built up from stretch, I really have no idea how much time the creator had invested into this. If you are expecting a text game like me, you could be totally owned. Awesome.

There are currently lots of issue. Balance. Bugs. Placeholder everywhere. But what is there can already make a pretty fun game.

My first run was stopped by a game breaking bug, turning my mascularity and all related numbers to NaN after a defeat... but it was enjoyable before that happened. I am looking forward to see a great game when it is more polished.

This game shows extremely good promise, keep up the good work.

Every day(every day is a couple seconds) that passes subtracts 1 kg of fat, which makes it nessecary to constantly overeat like a bear to build up food stores and prevent starvation. Stop that, make days go slower, make food system less obnoxious.


Edit: Vore options allowing you to recover food from enemies makes this more viable.
