Super unique take on the theme - genius! With a little bit of work on the collisions and friction, this could probably be a commercial game mechanic! Nice work :)
I had the engine working great with a flat plane but that all went out the window once I added the level structure. I had a repulsive force making the snake slide around easier, but it maxed Pico's CPU and lagged everything down. Thanks for the comment, really appreciate the support.
