Really fun little game, good art style and a funny interpretation of the theme.
If you continue to develop it I'd suggest small tweaks to the gameplay like adding a tiny bit of knockback to enemies when you hit them, otherwise it's easy to get overcrowded. Also maybe add a high-score board?
The only bug I found was that the high-score doesn't reset after game-over. Or it does, but as soon as you score points it reverts back to the old high score.
