Wow this was great, I was like YEA GUNS, BIG GUNS then realised there was Puzzles in my shooting game and not enemies and i'm ok with that :D
Art is great - the 1 high rooms felt a little claustrophobic, really liked the pacing - though with the platforming and shape constraints it was very linear. But with some enemies and more platforming elements I think this has some decent potential.
Audio was great I loved the music from the first gun and missed it with the others.
Great entry <3
