Wow, I have to give you props for probably your hardest game yet! I had absolutely no idea how to get most of these items, much less combine them. It was impossible for me to do anything without a walkthrough. I guess it was pretty unfair for me. I still didn't think it was bad. As the most prolific gamer, I feel so dumb.
Well, maybe I'm just so disorganized with my games. You have to click on the piece of paper to get a paper clip! Then jam the paper clip in the phone (?) to get the number for unlocking a desk for the screwdriver. You then look under the keyboard for the key. Dang, this is complicated!
