Not too bad
It's a well polished game and is really fun. The heavy DNB might not be for me but I can appreciate all kinds of music :D
One little gripe though, you've obviously taken a metric ton of inspiration from Space Invaders Infinity Gene which in my opinion wasn't that great a game.
I was never able to nail down on exactly why that game wasn't so good, because it had potential, but I always thought it took itself a bit too seriously considering the genre.
I probably came across as an unhelpful asshole with that feedback but I do really like the game :D
