I love the look of the game! It's very neon and reminds me of Geometry Wars a lot. That being said, I wish that there were some indications of some kind. Having no indication of what's happening at any given time sounds fun on paper, but without direction it ends up feeling a bit frustrating. Everything else is really cool. Great sound and art!
