Handling takes some getting used to but it feels really good when you're managing to use the walls to recharge your move/ fire, adds some interesting gameplay challenges. I think starting the player in a stationary position and letting them plan out their precise moves feels better than the frantic levels however. Maybe having a way to weigh your ball down to stop it bouncing so you can line up shots (as well as more precise turning) would turn this into a pretty amazing puzzle platformer.
