This was a really fun little 3D rage-platformer. The hamster ball controls felt surprisingly smooth, and the idea of rolling/spinning through a cute obstacle course fit the theme really well. I also liked the design of the ball itself, it looked way more interesting than just a plain sphere, and the music gave the game a nice vibe.
My main feedback is that the mouse really needs to lock to the game window, since the camera can get stuck when the cursor hits the edge of the screen. A little air control would also help, especially around trampolines or tighter jumps where you can get stuck bouncing. Some parts near the end felt a bit slow or punishing after falling, but overall this was really impressive, especially for something made so quickly. Great work!
