6+ (iOS 8.3)
Nice homage to arcade shoot em ups of times past. There are a few issues: (1) punishing difficulty even on the lowest setting, (2) lack of multitouch control, and (3) amount of time spent underpowered (especially during boss battles), as your ship loses power ups each time it is hit. It would be helpful if the next ship could continue with the same level of firepower.
