About

An AI-driven text RPG engine built around one idea: your character's body is never fixed. Start by shaping her hairstyle, eye color, and base build, hourglass, pear, apple, then let the story push that shape somewhere else entirely.

Everything runs through the transformation. Bellies and breasts grow or shrink, weight redistributes, pregnancy takes hold, and the 3D model updates to match whatever the current scene is doing to her. Since the AI generates the narrative on the fly, there's no fixed script to hit those beats on cue, so what happens to your body is genuinely up for grabs each run rather than a set sequence of predetermined scenes.

Added world edit button in gameplay to allow you to edit the world you are playing
Corrected memory calculations
Fixed abort button breaking message history

v1.1.10

Added an informative memory usage bar
Increased default endpoint memory from 2000 to 3900
Fixed the token count logic to be much better at approximating tokens used

AI can now suggest changing locations
World Editor Improvements:
Added duplicate button to every item (entities, stats, traits, ...)
Can now set one or more locations as starting location
If more than one location is a starting location, when player starts a new game the game picks randomly from only those places

v1.1.6-1.1.8

Dynamic Stat Logic: You can now write Javascript code to update a stat based on other stats! FULL GUIDE HERE
AI Notes
There is now a Notes panel in the left sidebar
Notes will persist for the entire game and get saved/loaded with the game saves
In the future, the AI might be able to update the notes, but not for now as that requires much more testing
Revamped Save Format
Resolved the exponentially growing save file issue
Old save format will be automatically converted when you load it with the new version

v1.1.5 Hot Fixes

Fixed major bug where repeated edits of a world will fail to save
Added abort button to stop generation early
Added the ability to disable the choice generation and stat updates in settings(this speeds up by up to 3x because the game doesn't update choices or stats)
Added the ability to delete stat updates in the traits editor

v1.1.4

Storing and Editing Worlds
You can now edit and upload your own worlds into the game, the edited/uploaded worlds will be stored and persist across page reloads!
However, you should still down load backups of your worlds as your browser data could be reset.
Source Code Released
https://github.com/FieryLionite/formamorph
Bug Fixes and Improvements:
3D model parameters (belly size, breast size, fatness) can now exceed 100%, previously the 3D viewer used the 100% percentage which meant you could never exceed 100%, even if maximum belly size got increased to 1000.
In-game Location tab description showing the AI prompt instead of in-game description of the location
Removed file size limit of 5MB when uploading music or images in world editor
Load menu: move download save button to front, move upload save button outside scroll. Previously small phones couldn’t download save files

v1.1.0 - v1.1.3

Added quality TTS (only available on Chrome and Edge)
Added language selection
Improved responsiveness by 20x times! You now see narration text nearly instantly rather than waiting up to minutes for the AI to finish writing the entire response.
Removed the complicated JSON formatting, the AI can now respond in a much simpler format, this should greatly increase the success rate of parsing AI responses and allow you to use even regular role play AI models!
AI can now see player traits information and more accurate stats data (including current and max stat values along with stat descriptors)
Note that the AI still cannot give you or remove traits
The Stats panel now show +5 or -2 in front of the stat names to indicate change
Added default setting to limit AI event to only one paragraph (this prevent AI from writing too much and going off-road, eating up precious memory tokens)
Added the ability to edit the AI responses and player stats
AI can modify the maximum value of stats
Fixed bugs:
Entities list now work
3D character viewer often didn’t load the customization data

v1.0.3 Patch:

World Editor:
Added option to toggle the 3D character model or not for that world
Fixed major bug: Stat editor doesn’t show a stat min, max, or regen values
Added 2 new worlds: Valentine Survival and Reincarnated as a Drone

v1.0.2 Patch:

Error messages are now way more informative on what went wrong
Revamped the entire save load system to use IndexDB to avoid the 5mb localstorage limit
You can now download and upload save files
Reset AI settings now also reset the system prompt
Fixed bugs
Game text showing nn instead of newlines
Traits applied max stats incorrectly

v1.0.1

I sold a kidney to temporarily rent 2 more servers to match demand lmao why do I have to do this I’m poor as fuck
Also fixed some bugs and added a notice to follow the open router guide because its free to use the models there!
EDIT: Based on the logs it seems to be relatively stable now, no more dropped requests

v1.0.0
