This one was good overall. For improvements, I’d suggest adding a sound effect when the ball hits the floor, and some kind of visual or audio cue to indicate when the player should jump, so the ball can go higher. I couldn’t finish the game, but I did reach the gravity ability section. I was a bit confused about where I should go at that point, but I still enjoyed it great job.
I did notice a few bugs: the ball’s collider stops working when its velocity gets very high. Also, when switching between the ball and the spider (or vice versa), the collider sometimes stops working as well.
Overall though, good job.
