An absolute steal. Fantastic presentation, compelling story, addicting gameplay loop, and an absolute banger of a soundtrack. Story elements are presented very well, brief, and as far as I can tell, entirely optional. Plenty of build variety and optional upgrades to keep you engaged. This game is pretty hard, but it doesn't feel impossible, and I'm a complete newcomer to bullet hells. Definitely worth your five dollars, and if you don't think so, try the demo. 9/10.
