That was super fun! I have a video coming tomorrow, so you'll be able to see my experience. The level with rapid spinny-things broke me, haha. After having the entire level figured out it was punishing to trial and error after going through the whole thing, so I had to give up. That said it was super fun, simple and smooth with controls. Very easy to know right away what the cube is capable of doing. I really enjoyed it!

Kinda weird game, but that makes it challenging.

The physics are my main complaint. The air movement goes slowing down until you press another key, then it goes full speed again. Because of this, I dodged most of the obstacles by jumping out of the level then coming back.

The graphics are just Unity geometric shapes. Nice job with the music, but I think it lacked sound effects.

I don't know what part is meant to be "unexpected".

Overall, the physics makes it a bit frustrating, but I enjoyed playing it.

Nice challenging runner! But that music! Ugh! I just kept waiting for some dark twist or a screamer, anything to make that music gone. :-D (It did on the last level! I don’t know if it was intentional.)

Controls were a bit hard and I got “Game Over” a couple of times for no reason, probably some glitches in collision detection.

I also think it would be better if you provided the game as a Zip archive, not an installer. That’s a common itch.io convention and this way your game will work with itch.io client.

Just my suggestions. Overall, great game!
