The art is awesome! And the music goes well with the action, I liked the "win some, lose some" mechanic after every round in the sense that the traps also hurt you.
One of the weapons I bought (one that threw purple balls at high speed" glitched at some point and stopped working, which was a bummer because it was the best weapon I had up until that point!
I liked the "more assembling required" message, thought it was a clever use of the theme :)
Great game, wish to see the full thing!
