I really wish the running animation was better, because aside from that this game is visually SO STRONG. The colour separation when you shoot and the enemy animations and the way the space changes is all elegant as hell and I love it.
Game also just feels really, really good. The little bit of knockback combined with the colour separation stuff just makes it feel really, really nice. Great job.
Also one of the best implementations of the "Entire Game On One Screen" theme that I've seen.
