While I think the concept is interesting, I don't think it works, at least not with that level design. There are times where you are just waiting for the ball to get in the right position and that can be frustrating. Keep working on it anyway!

Wow, this game is crazy hard. I couldn't get past the first room! Above all else, I'd suggest you try to incorporate an appropriate difficulty curve – start out easy, with no punishing red walls, then slowly introduce more hazards (along with checkpoints of course).
