I like your interpretation of the gamejam theme! The game world is easy on the eyes, and the different gun types are neat. The hue variation effect on the enemies and the walking animations are nice touches.
I can't rate the gameplay because I don't think the game ran as intended on my end... bullets from both the player and the enemies would either disappear immediately or decelerate and freeze after a short distance. If you want to keep working on this project, let me know and I'll give you my specs to help fix the bug. I didn't hear any sound from the game either, in case there was supposed to be.
Gameplay and sound aside, nice work!
