Sorry about that, that was an incomplete version. The full game is now up, which gives you the elevator codes you need to get to the next floor. Hopefully there are no more serious bugs, but let us know if you have any further input as we continue to polish the game.
I was running around for hours and I thought I was missing something, but what I was looking for was never there to begin with. I'm glad I'm not that blind yet :). Later I'll play it again and if there is some bugs I will let you know. I'm going to make a video too if that's ok!
