I really liked the art style until the So Friggin High level. The nearest edge of the right rock is impossible to see, so it's really hard to get a line on the center of the stone, where the recharges are at, especially when the camera is moving around with the ball.
That out of the way, this is really good, and I'm happy to say I placed on a few leaderboards, which I don't think I've ever done before. Really impressive work, and a lot of cool mechanics. Great job!
