Well, it's cool! Perfect mood from start to end, it nearly feels like a finished game already, I'd say it lacks a few VFX on some scenes or actions but that maybe just me. Musics are so good they felt like it came from a Zelda game. I felt the gameplay was a bit too simplistic on the tuto boss but thinking on it on the next bosses, it's great the way it is, very neat action, like a Megaman game. The clostrophobic feeling of those small rooms on a black screen really adds to the game too.
Cool cool game!
