I beat the boss, barely. Pretty cool arcade shooter which looked appropriate and was easy to pickup. The boss was well done and gave a real bullet hell feel but was still beatable so it was balanced very well. The second stage did also not work for me so I'm not sure what the issue is. The background music was a bit strange as it was soft relaxing music but I expect some upbeat music for this kind of game. Overall pretty neat and if you're gonna add some powerups or more bosses that would be cool. 

I beat the first boss! I don't know if it's intended to end there but after that no more enemies would spawn. Regardless, it was fun for a few minutes.
