I very much enjoy weird physics games like these and it captures Getting Over It well. My two main pieces of feedback is moving the reset key away from the movement keys since it happened quite often while trying to move around that I reset my progress which was somewhat annoying each time.
I don't know if the other thing is a hidden feature or bug but around the "Hard Work Beats Talent" poster, Ludwig becomes a lot "heavier" in a lack of a better word. If the arms are on either side at this point, he's basically stuck and can't move while earlier in the level, he can lift himself up with just a single button. This makes the barrels very hard to do even when you've figured out the controls and it feels odd that the character behaves differently with no feedback on what could've changed it.
But I do enjoy it either way. Getting Over It is one of my go-to games to when I just want to relax and this very much has the potential to be something very close to that!
