Holy moly! That was certainly an interesting experience. I really loved the idea of having your bullets be dangerous to enemies and yourself. I certainly made my life much more difficult as I played through the game, but I still had I great time. There's a lot of content for a 1 week jam game, and it told a pretty good story. The final boss was fun and challenging, but a little bit stale (though I can certainly understand if you didn't have time to implement as much as you wanted)
Overall, it was a really cool game, and I had a fun time :D
