>the entire upper chest area still counts as heart I believe
The heart flag was a remnant of the original code and used a very crude detection area. I improved it somewhat, now it should yield more correct effects

>to then detect wounded areas
It's possible now to detect if the pixel under the cursor has no visible skin, but has a visible part of the meat layer sticking out. Sadly this detection is extremely slow for continuously detecting tools (e.g. marker or lighter), so it's not enabled globally. As a test I added it to the bb gun in the dev version, so you should see a difference now when shooting exposed parts.

(Dev version is still available here: https://gitgud.io/zmod/torture-chamber/-/archive/master/torture-chamber-master.zip In order to use it with the existing executable, replace the relevant parts in resources/app/static/ with the contents of the zip file)

>implementing a character creation feature in the near future
There are no proper open, ready to integrate character creators (for both 2d and 3d) out there and not without reason. Building one from the ground up is def not a regular sized update, especially if you consider all the special requirements. Even stuff like kisekae only offers (afaik) a single flat shading style.
With that said I'm collecting vague ideas for a future, 4.x.x update. It's something that might never materialize, but it would use a rigged polygonal mesh for the body (like stuff in 3D but flattened in 2D), which could allow morph transformation using predefined sliders as you would expect in a character creator. This approach could offer additional features (like bone breaking, bouncy boobs by having a separate breast mesh, etc)
Back to version 3.x.x, the documentation for characters is complete, so you can already make your own now – provided you don't mind drawing the assets for hair and eyes and everything you want to customize.
