I like it. The art was nice, the music was pleasant, and the gameplay was enjoyable. I would suggest making the enemies be able to pick up the same items as the player, instead of different items. That would introduce competition for resources between them, and give the player a reason to continue trying to pick up items even after they've collected a virtually limitless supply of ammo. The flamethrower weapon could also use a rework of some kind. As is it is by far the most powerful weapon in the game, and also obscures a lot of vision.
