I like the art, but there isn't enough feedback to make it engaging. Perhaps you can add some more impact effects. Also, at one point I had a different weapon (shotgun), but then it switched back to the default weapon again.
It was game jam entry so a bit limited time wise in that sense :) I think shot gun was temporary power up in that game.
There is unused paste knife in the game as well, I think you access it with pressing 1, I can't remember if it actually works :D
