Hmm, interesting. The rolling movement is quite fun!
A lot of the enemies seemed to be invisible? I kept taking damage when nothing appeared to be on screen, and a lot of bullets seemed to impact something invisible.
The art is pretty good. That title art is killer!
The audio is quite imbalanced. The gunshots are louder than the intro music, and the player damage sound is VERY loud, peaking at +1.9 dB!
All-in-all, good work. Congratulations on the submission!
