Realistically this game is around a 3 for me, give or take. It can be a 2 at times but I can see this growing to a 5 easily if it makes the right choices. Overall, at the state it's…

Many people are just giving 5 stars because of the art. And it is true the art direction is wonderful, that's where it ends for me, this is clearly a demo, as there is no story, barely any different environments…

I love this guy artwork forever and when he announced that he was making a game as well I was estatic, AND HE DID NOT DISSAPOINT. I recommend this to anyone that loves fighting sexy monsters with crispy pixel art.
