Hi Mugsy,
well, there
is one sequence in MOS (very close to the end of the game) that you could call "timed".
We decided to include it because time is actually of relevance there. Giving the user all the time in the world would have spoiled the feeling of threat and pressure, and both is an essential part of the narrative at this point.
But be assured, we know that many adventure gamers
hate timed sequences. That's why the game will automatically give you the opportunity to try again in case you haven't made it.
In short: No need to worry.
