Love the art and animations, very polished! Reminds me of Earthworm Jim.
Tuned a bit too easy - I didn't even realize i had a trash can shield until it was over, and no health bar or anything. Tried it again and the shield was just too clunky to use. Was also a bit jarring that if you shoot while jumping, you lose all momentum. Feels like there should still be some follow-through.
I also liked the variety of enemies and they all held true to the junk yard theme. The one with the "headlights" was a bit strange though.
