Speedza Modding!
https://gitlab.com/underfelt/IndieModding/-/tree/main/Speedza
First follow the instructions in Installation and Bootstrapping/Readme.md to inject oxide into the game, then check the Mods folder for mods to load in. I've only got JumpButton right now which lets you hop and glide - if other mod devs would like to get in on this, file an issue on gitlab and we can chat - oxide is pretty easy but might feel weird if you haven't modded with it before. Also I need help finding good hooks.
Mostly these instructions here are intended to give fellow fans a way to make your own mods relatively easily
I am not associated with the project and doing this independently - if you run into trouble with this please don't bother the devs, submit an issue in the gitlab
