Oh this one is great! Big props to the composer that worked on this entry, the track fits the whole chaos in the game really well and I'd love a release of the track on Soundcloud or something.
Presentation wise, I like the minimal use of red to signify both good and dangerous things. I think the hitboxes might need some work as most of the enemies that touched me didn't hurt me (Unless this is meant to happen) and a few of my shots seemed to go through enemies at times. Nothing that took me away from the experience though, and I had lots of fun playing this one! Rated.
