Really nice jam game.
I've seen a couple games with similar concepts to his so far (controlling the character by walking around a controller) but this is one does it best in my opinion.
Love the juice. In particularity the explosions. Nice graphical effect, nice sound, nice level of screenshake, and i love that the pitch increases with each consecutive hit against an enemy to signify how many more hits are needed (this also has the added bonus of making the sfx much less repetitive).
This game could have easily been too hard but i think you got the difficulty just right for a jam game. I appreciate that the enemies on the first few levels don't shoot back so you have a safe environment figure out what to do.
Good job!
