How do you do it?
I just played all of the Submachine games and this is my favortie. First of all it a lot harder, the puzzle require more thinking, but I think that what adds charm to the game. I also think it cool that in this game you can use your secrets to view bonus material, if you can find the room. Very creepy, and I'm still not sure of what to make of the ending, but hopefully another Submachine will explain.
