Very cool idea, I really liked the graphics and the audio, I would say the sound effects were a little to loud for me and it didn't let me hear the music, also you can just spam the shooting on top of you head and you won't get killed ever so that made the game a little easy, so I would suggest maybe making the projectiles bounce more so that the character has to actually aim for them and also maybe adding an explosion radius so that you cant let them get to close, but those are suggestions if you ever plan on expanding on the game, for a game jam the game is cool and I really liked it :D
