On my game, the player has to survive for 2 minutes to win. I made a countdown timer by creating a global variable of 120 that is reduced by 1 every second, and a textbox at the top-left shows this. However, instead of it saying "90 seconds left" I want it to say "1:30 minutes left." Is there a way I can do this with my current strategy, or should I switch to a more efficient way?
