Love the theme, the sprites are great and movement feels good. I like the fact that there are multiple levels and boss fights, however on the first level I found that since all the enemies move towards you on the Y axis you can just stay in one place and keep shooting to kill them all. I also had a problem with shooting since I was playing on a trackpad and having to click was a bit awkward, but this wasn't a huge problem. Overall a really solid game, congrats to the whole team!
