Very fun mechanic! The game was also way longer than I expected and I ended up playing the whole thing :) I wish the blue tiles were broken up by a few different designs, since it starts to get weary on the eyes seeing the same pattern when going super fast, and one thing that really hurt my enjoyment is the momentum system on the ball, as it often felt like I was skating on ice, especially so in the levels that upped my speed. Now, i'm not sure if this was intentional to make it harder, but if it was, I don't think it fits well in a puzzle game. A similar thing about flipping gravity, I feel like it takes a second too long for things to fall up/down. Otherwise, very well done entry with fun puzzles!
