This was a blast! It's simple, sweet, and to the point. You mention it's "not the best interpretation of the theme," but honestly, sometimes a simple interpretation is best, and I think this fits that bill.
The audio design really pulled me in, and the screen shake gives the game a really great feeling of impact when you collide with the enemies. I'd love to see what this game could grow into given more time and the opportunity to expand on it.
Great work!
