It isn’t specific to platforming. It has a ton of features. It has a “Sprite Font” system, a 2d button system, a console (like you would see in DOOM), data management, music and sound management, and a runtime for a scripting language that I have been developing.
It is still an early WIP. It has been a pain trying to get it to play nice with WebGL. Hopefully after I have participated in a few more jams it will be ready and I can release it.
