Cydonia: Mars: The First Manned Mission

Relevance:
Almost all were irrelvant to plot and setting.

-----
Real-time:
*) At the beginning, you've got a few minutes to dump the fuel cells, put out
   a fire, patch a leaky visor, and free the captain. If you fail, bad things
   happen and you have to restart (but you haven't really done anything yet,
   so not a problem). Once you get the hang of the controls, it's all very
   easy. You might not ever know that there was a time constraint.

-----
Reasonability:
Some puzzles have arbitrary solutions, i.e., there are several possible
solutions, and you just go through all of them until you get the "right" one:
*) crypt locks -- no connection between the character and the door
*) judge crypt -- top to bottom, bottom to top, left to right, right to left?
   all are reasonable, and the interface makes it tedious to run through all.
   also other feasible patterns based on the lines...
*) scholar crypt -- why all the make-work with the cards and the drops? and
   when you're done, there are again several reasonable orders, tedious to
   run through
*) control centre chair -- "on", "start", "go", etc.
*) millstone -- dozen nice patterns, with no clue given to the type of pattern
   it wants -- a riddle would have been good here

Other bits of unwarranted tedium:
*) the planets puzzle -- okay puzzle, but then you have to repeat it an
   additional 8 times using a bad interface
*) merchant crypt -- opening the drawers
*) pyramid pieces -- nothing but pixel hunting, and the actual construction is
   just trial and error

And, in the dirty tricks department:
*) ambassador door lock -- uses the interface to purposefully conceal the clue,
   fortunately it's such a trivial task that you're likely to trip it open
   without realising how

-----
Difficulty:
*) flower riddle -- good riddle, where the answer is an action
*) activating control centre chair -- the place for the capstone doesn't even
   appear to be a "place"; the activating word is one of dozens or feasible
   commands, and its sense relies on knowing what will happen, which is not
   clear from the layout
*) whale puzzle -- good puzzle
*) chasm riddles -- good riddles
*) underwater tetrahedron colour puzzle -- the tough part is realising which
   machine you have to match the colours with
