I just restored the game and got to play the rest of it. :D
And while I feel like I'm running out of fingers to use (jump on space instead of W might've helped with this) and properly control my dice, this is a much bigger game now than what I thought it was. The bumper up on walls feels really good!
If you allow me the nitpicks: I do feel like the dice is moving too fast horizontally, making it hard to control. The superjump also seems to be inconsistent, giving me various different heights and thus leading to frustration especially in spots where you die if you don't manage to chain superjump into a dash or something.
Unfortunately I somehow managed to break the game where my dice stopped moving entirely. But hey, it wouldn't be a GameJam if the game didn't have plenty of bugs amirite? xD
