Really original take on the theme! The enemy AI seemed to be quite good, and the game wasn't insanely difficult (which is always a win). The story was pretty cool and I liked the joke ending haha.
The only issues I had were that
1. (as others have said) the game felt quite empty without music.
2. I think the boss fight would've benefitted from giving the projectiles a new sprite and some more complex behaviour.
3. As good as the art was, it was not black and white which is a very important rule for the jam.
However, these issues (with the exception of 3)are very minor and do not affect that this is a really good jam game, well done!!
I would appreciate if you could rate my game aswell :)
