Very fun game! Your minimalistic design and game mechanics fit perfectly into the jam's theme. Adding on more mechanics was a very interesting approach. It definitely ramped up the difficulty and made me feel skilled anytime I got past a seemingly simple obstacle, haha. Controls are mostly spot on. Only tricky thing I ran into was anticipating the momentum shift while jumping up and over when the cube got smaller. The mechanic itself is great, it was just a bit floaty and hard to control. Fortunately, the game doesn't punish death too bad at all, so it wasn't too frustrating. Overall, very fun unique game! Good work!
