The art style is incredibly, but unfortunately this game is let down by its design. I couldn't figure out how to complete the game, and it falls apart when the train becomes monstrous, with extremely loud noises which I had to turn down.
I think the premise is awesome, and the idea of the drawing blood and sacrificing mechanic, but it needs more explaining and feedback as I never knew if I was doing it right... massive kudos to whoever made the art!!
