Broken Sword: The Shadow of the Templars

Real-time:
*) toppling the totem pole -- minor, but why the rush? it's dark, there's
   no reason for them to see you
*) stopping the train -- minor, but there's no time to try anything else
*) the goat -- minor and fair, retryable
*) hiding in the sarcophagus -- minor and fair, retryable
*) the cat -- minor and fair, retryable
Maybe missing others here, but they're all minor.

-----
Reasonability:
Silliness:
*) getting around the goat -- Not only is it very contrived, but there's no
   reason to match the input actions required with the results.
*) the cat -- The resulting action isn't determinable from the inputs. Why
   should it work just then, but not when the cat is elsewhere?
*)  finding the mirror at Vasconcellos -- pixel hunt
Sudden death syndrome:
*) going left on the train roof -- Who'd a thought George would be so stupid?
   He should have just mentioned that it looked too dangerous (it's not
   clearly dangerous from the angle we see things).
*) choosing to explore the stairs before the crack underground -- Completely
   unforgivable. There's no reason to think they're even connected.
*) die like a dog and die -- What evidence is there that this would be worse
   than choosing the other death? It's more in character, but you may be
   trying to outtalk the other guy by saying "die like a dog".
*) not jumping from the cliff -- There are loud hints that this is what you
   should do, but the only alternative action seems very reasonable, too, but
   it leads to death.
*) leaving hotel with manuscript gets you killed -- It's easy to do this
   without having been warned about the danger.

-----
Difficulty:
Mostly it's very easy. The harder bits:
*) lighting the candle at Vasconcellos -- a nice, tricky bit
*) the goat -- because it's silly and contrived
*) the totem pole -- because the result is not obvious from the action
*) using the chalice on the pattern -- too bad there's so little else to do
