I loved the graphics, it fits so well, and the game is so well polished. The gameplay was a lot of fun, just missing an easier way to get more drones, getting a few flying rocks that you can barely see was pretty hard with so many bullets on the screen.
The performance was painful, most of the time I was playing in slow motion, even with only 2 or 3 enemies on the screen (I was playing in the executable version), I am not sure if this is an issue with my hardware, but it was hard to continue playing.
