I liked it! It was brutally tough, though. I liked the difficulty level, but it was frustrating at times because I felt like I didn't know how to use the push/pull attractors effectively. It would also be great if the game saved upgrades as you collected them.
I honestly like how the ice cube looks, even though it's very minimal, the beveled transparent cube is *chef's kiss* perfection. The overhead view in the corner was also hugely helpful towards making jumps, though it would have been even more helpful if it was an isometric projection camera instead of a perspective one. Nice work!
