It's an interesting idea, and it feels very chaotic. Visually, the particle effects are very nice, and the main character is quite cute; though the various sprites feel a bit mismatched in style. The sound effects are nice, though having a few more (eg for the gun moving) might be nice. I like the idea of having the player and the gun separately, it seems like this can be an interesting mechanic, though I don't see why you should only be able to move the gun a few times? Also, the fact that you can stand on enemies is a bit weird, but it did lead to some funny moments, like when a tiny bat took me on a journey.
