No. Well, it depends. If it's the whole 'you have for example 5 minutes to get out of a tower or else you die' then why would you have to be at the door before you die? Wouldn't die before you get to the door? Look, make a parallel process event on the map (if it's only one map, if you start on one map but the door is another map then you'll either have to copy+paste the event to each of the tower maps or make a common event) with a conditional branch, the timer is on bottom of the first page of the conditional branch option. Set minutes to 5 and leave the 'or More' the way it is. Hit OK and then put whatever you want to happen if the timer is over 5 mins to happen, like show a text and transfer the player back to the beginning or bring up theload screen or w/e.
I suck at explaining things -_- It's really a very simple thing you're trying to do so if you don't understand what I said just ask.
