Thank you so much!
Yeah I clearly underestimated how hard the movement was with the slight slipperiness, and it's most likely frame-rate dependent unfortunately, part of doing my own bad physics lol. The Windows build does also have much better performance for some reason, so it's very likely easier there. And no, I don't know what the conditions for objects to either push you or clip into you are either lol, that was entirely based on a bug in my code that I made into a feature, although in some very few I did disable their collisions so they couldn't push you out if I didn't want them to.
Also thanks for playing it to the end!
