Great game
This is a fantastic bullet-hell type game. Unlike some of the other posters here, I think the controls work well and the difficulty level is appropriate. I have also played through the whole game (except the recently added mission) without resorting to in-app purchases, so it is definitely possible.
I am also impressed with the recent update. The developers have made a excellent game even better.
