Ha! I love how you went for all the super fast endings. Watching you explore through all that was wonderful, my dude. Thank ya for taking all the time to make that - and just for playing it. Super frickin cool.
In terms of what to do next - based on all the confusion from pretty much errrrybody, I clearly need to explain the entire game better. But! There are two ways into the locked apartment at the end of the hall. There's a door with a dead dude hanging over it that will give you a key and if you solve the power puzzle thing, the dude who can't hear you will give you a key.
The power puzzle - which Im realizing is *very* poorly explained in hindsight - is basically just the board game operation and some math. Each circuit breaker has a number and if its powered, it adds to the total power consumption of the floor. the power thing can only go as high as 38 or as low as 28. So you have to move around the pieces so you can successfully remove the circuit breaker to the dudes apt who cant hear you without going above or below those thresholds. I realize thats far too complicated and far too hidden in game to be of any use - but thats how it theoretically works.
