*) Crawling through the ducts is played out like a platform game, although
   without death or any real-time issues.

-----
Real-time:
*) Putting the green goop on the eye -- you get to repeat until you get it
*) Shooting Borxs in the hall -- I don't think you can die, and I don't even
   think you have to hit any. It just seemed to go on for a minute or two,
   almost like a cut-scene. Maybe I hit my quota.

-----
Reasonability:
*) Use the cyber-crown on the typewriter -- but it's not electric!
*) What's the combination? -- you have two digits of three, leaving way too
   many possibilities (don't know they're the last two)
