The Journeyman Project 3: Legacy of Time

Relevance:
*) end-game puzzle -- an irrelevant logic puzzle, but the game needed something
   here; it's better than an arcade sequence

-----
Real-time:
*) grabbng Khan's sword -- fair: there's a fairly big window, and you just have
   to get up and try again if you fail

-----
Difficulty:
No very hard challenges. The toughest were:
*) end-game puzzle -- simple minded, but large enough to take a while
*) dousing the flames in El Dorado -- clever puzzle
