Great game !
Just, when you're in time warp, walls lose their solidity, but I guess that's because we're moving so fast xd
HAH! And here I was frantically fixing and testing walls, but forgot to test them during the time warp. Thank you for catching that!
EDIT: It didn't occur to me until now that timescale also affects physics calculations (even though I was programming to account for that the entire time LOL) guess I forgot about the walls and their collision calculations
