I liked a lot about this. The simplistic art and known gameplay worked really well to focus on what was going on. The controls were a little tricky and I wish there was a way to move without charging (or could continue to move while charged in some way). Also, I may have missed it but I could not see my health in any manner in game so it was tough to gauge how good/bad I was doing. The feel as you group together a bunch of circles and then get them to pop together was really satisfying.
