Very impressive. My high score was 1729. The music was really good, and the graphics looked very nice, especially with that CRT filter. The A/D keys didn't work for me, but the arrow keys worked fine and I was able to play no problem. I like how it causes you to split your focus over the whole map.
Also, that cover art it pretty amazing and definitely got my attention.
This is a super interesting concept that I really enjoyed playing. Keep it up!
