i wonder if it's possible to replace the player model within the files if possible, just for fun really
As it is now, it doesn't support ability to mod anything. Since this release, I learned to add mod support, and it is high priority for an upcoming versions/reworks. But I doubt it would be worth backporting modding to this project, since it would take some rigging effort to adjust models to skeleton I use here. Unless rigging doesn't scare you?
