Geez I got addicted to this very quickly. Bosses are a good change of pace. Shop keeps you going to get the next weapon. Graphics, audio and control all on point. Amazing one! Only thing I'd mention and this is personal preference, is the dash: It dashes where your character is looking towards rather than the direction you're moving to, and normally you'd be running backwards while facing and shooting at enemies. Got myself headbutting the zombies a couple of times because of it xD.
