SPOILERS, but I need help:
I've clicked everywhere, and I can't get out of the first room. I found 3 keys (2 opened drawers), a cassette, a mysterious box, a ring and a metal thing that go on the box, and the last key I have won't open the door. There's nothing left to click on....what did I miss? Oh, I also got the power cord and turned on the CD player and the empty CD case.
