That part where you bounce of all the singles was incredibly satisfying! With most of the other levels though, I found myself running around aimlessly until my bar was full enough to collect the next die. The bar seemed only loosely dependent on my velocity, so I never really knew exactly what to do other than just flail about until it somehow charged up enough to collect the next dice. Also, I got stuck on the ceiling sometimes and don't know why.
Overall, I like it! It's nice that the difficulty wasn't so bad that I couldn't finish it (unlike almost every other game I've reviewed so far)
