Simple idea but incredible execution, as soon as i grasped the concept it was very satisifying to play. The only critique I would have would there appears to either be some sort of bug or some sort of problem in the way the game communicates the "powered up" state as I found that multiple times I would become powered up, start going around smashing circles and then suddenly die. Other than that the level of polish is superb and I am very impressed with this game
