Sorry, but I’ve kinda abandoned this project. It used a lot of imprecise collision and I moved on to my mini-tilemaps extension I may update that with performance improvements, bug dlfixes, and the actual ability to use slopes though eventually. I’m currently working on other projects but may return to that project in the future, not sure when. I also believe you’re using a modded version of this post? The sonic physics demos I don’t think I’ll work on anymore, but the mini-tilemaps should be a good replacement if/when I get around to updating them. Hope you understand.
