Omg I just went back to the neutral page to check which one vision is, and FUCK if that isn't the one that kept me up until 2 in the morning last night. I have it memorized by heart because I spent so much brain energy in that damn room.
the screwdriver handle is in the left desk drawer.
You have the box with the little glass bubble on top? "examine" it and click the little tab just below the bubble to open the flap, then put the marble in, close it, and look in.
I started that one but haven't gotten very far. I haven't found any that I like as much as the Neutral ones, most of the graphics are so crappy. The neutral series spoiled me.
