This is incredible work. The gameplay idea is very simple but it works well.
I was impressed with the amount of effort you put into each level and how many different gimmicks you were able to create (like the dark holes and the ghosts), despite not changing the core game too much.
Just a quick constructive feedback: I found the gameplay a bit too janky at times - I understand that is the idea of the game, but that being said, I feel like there were times where it just became completely out of control and it became frustrating. Slowing down the cat's spin speed or maybe adding an additional boost could help get control under player's hands and make it a bit more fair and gratifying.
Great work!
