I played the game and immediately there was a problem, the physics are completely broken. most non-physics animations are fine, but walking or jumping doesn't work. walking causes you to "stutter" along the ground, and jumping has no momentum, and can't reach the platforms in the second room. my theory is that every other frame, the character is being put back into an idle state. I want to play this, and I paid for it, but it is currently unplayable for me.
edit: I have a controller plugged in, so it might have to do with double-input reading, I also have windows 10 in case that helps. good luck debugging it
