The initial level's background looked rather blurry, but once I was in the boss fights, with the much nicer backgrounds, the overall visual aesthetics looked quite nice. I can see why you'd recommend controller, but I didn't mind the controls on keyboard. The music was nice and there were a decent amount of SFX. There were a fair few unique boss attacks, which is always nice. The mechanic is also interesting, having to dash towards danger to deal damage.
Nice submission.
