I quite enjoyed this game. The music made it relaxing and something about the square rolling around was appealing to me right away. I think the puzzles are well thought out and discovering what the secondary abilities could do was cool.
My biggest gripe was with the controls. The feeling of rolling along was nice—for some reason the inertia felt good to me here—but the jumps were where the gameplay becomes frustrating. It felt like it would often have a hard time detecting whether the shape was grounded or not, so I'd often not get a jump from keypress because the shape had just bounced off the ground slightly.
Overall a pleasing, slower-paced experience compared to many of the typical actiony types pf submissions.
