So there are 3 doors? Stage VI, Stage VII, and the power levels door?
...Whats behind door number 2? Or is that just a button against the wall?
Also, is there any sign that the electricity we're all instantly assuming is running through the floor right now is actually doing so? Is there a smell of ozone, a humming from the floor, or any electrostatic stuff (hair standing up, older type teeth filings humming)? Seeing as how all those bars are at the bottom, it might be off.
