Great game, I loved the way the attack feels. Also, this is a very clever take on the theme of the jam. A job well done, I think you if you spend time on this after the jam you will be able to create a really cool game.
Also, I encountered a very minor bug where the enemy can get stuck in between a platform and jitters in place. Not sure if you are aware, but here is a screenshot just in case:
In any case, great game. I had fun!
