The Art and the Music are very good, and the gamplay feels nice aswell except if you're jumping against a ceiling and you just stand in the air for a short time. I also liked the concept of shooting your money but it didn't really feel that different from just having ammo, i would have loved a shop or something else to do with the money that would add an interesting decision (do i buy this item to get stronger, but i can shoot less often or do i just keept the money so that i'm able to miss more). also the game (especially the boss) felt a little easy but thats very hard to get right in such a short period of time. All in all i really liked your game, good job!
