The first mobile shmup I can respect.

It's tailored specifically for mobile as opposed to being a port of an arcade or console game with all the issues that entail. Bullets are made large and bright for visiblity, controls are simplified (shoot automatically, slide to move, double-tap to bomb), and stages are played one at a time rather than making you do a full run that's 30 or so minutes long.

My only real issue is that the framerate is lacking, at 25-30. But it's still quite playable.
