I've managed to get the bus moving, get the shoes, and have gotten the padlock key from the bum. But I'm stuck. How do I find floor numbers for the elevator, or else what do I do in the tent?
I figured out that I should type in 999 and -999 for floor numbers, and have gotten the ship model and blown up the sign. I've also opened up the lamp and gotten the power flowing. But beyond that I don't know what to do.
