Mainly helped out and chipped in while my partner played through. Really good game to watch along with. Thought the difficulty was well pitched. Some sections dragged on a little but the last quarter was fantastic and enjoyably paced.
Had to delete it because I was playing it all the time and wasn't as good as I wanted to be. Its a phenomenal game though. Incredibly simple but so well honed into a quick, satisfying experience. Too good really.
