It was good
There were some errors:
The music doesn't loop, so it stops playing after the song is complete.
On level 13ish, one of the guys that spins and tries to hit you became indestructable (my weapons didn't do anything to it), and I couldn't progress.
The game isn't terribly original, but it is good for what it is. It is very much like phoenix down style games. The style has also been done before, but it was executed adequetly.
