A neat little shooter, but it didn't feel particularly punchy. It really did need some time spent on adding a bit of juice - camshake, things like that. There seems to be a lot of content for a jam game, which is a good thing! But I think in the future, less content more polish would be better :) the music was good, if a little repetitive after a while.
I didn't really see much theme application, but overall it was a good entry and you should be proud!
