It was an enjoyable experience. I really liked that you used the theme of the game jam as a game mechanic rather than just a time limitation to achieve some goal.
The music goes hard and has a good rhythm, which immediately made me want to play the game like a rhythm game.
The game has a good variety of enemies, which creates an interesting challenge.
I was surprised that turning the weapon in the same direction counted as a move. I felt that it didn't really fit the spirit of the game, where you're always supposed to move or change direction of the gun, even if you don't want to.
It was engaging and fun. Good job!
