The timed choice ends eather in the time (if nothing is tapped) or as soon something is tapped
So if reader taps red the time will stop even it is a wrong choice.
you will then with goto/label send him back on start of the minigame
So the game and with it the timer/countdown will start over again from start
…
Theoretically if you want each time to have different timer in the minigame - you can do it I believe only as several timed choices one under another (each with different time)
Each time reader ends one timed choice he goes to the next one… but I am not sure this is what you imagine
