A fun game, and it feels rather complete for a short jam. I liked the art and music, and they worked well together. The use of audio was generally good, and enhanced the experience, though the voice in the boss level did get quite annoying and repetitive. It would be great if the weird fade that happens when returning to the menu screen could be fixed too. Good job on getting several enemy types implemented with different behaviour that I could quickly learn and develop a strategy for. The difficulty level was also well balanced for a jam game. I've played plenty that were far too difficult, but I was able to complete this after a few tries.
