Too many buttons with no labels and no antlines, and therefore no way of knowing what the buttons do without memorization of what the room looked like before, assuming you can even see the change. We like most of the series so far, but this one gets a double downvote.

this one's truly horrible because you dont know when you've progressed, there's no sound of doors opening and huge lack of the glow patterns, you end up running in pointless circles

stucked in the second room :S

sounds cool
