I enjoyed playing around with the physics of the ball. The fact that it bounces off enemies/walls, and the fact that main character can catch it when it's near the ground made me stick around for a few minutes just to play with this mechanic
I got overwhelmed a bit with how much stuff starts happening on the screen after about a minute of gameplay. Although watching my character keep bouncing off enemies is funny, getting stuck in that state for 5-6 bounces kind of keeps me from enjoying what's fun about the game, which is playing with the ball physics
