Timers are similar to counters, except they are the opposite (they count down instead of up). They also can be displayed on the screen. First set the timer for a certain number of seconds by the B7 command. Then start and show the timer by the B9 and B5 commands. You *can* start the timer but not display it on the screen, for a silent countdown, using the B6 Hide Timer command. In this case, we choose to fail the objectives by doing command F9, then exit the level using command D2. And to be safe, we do 05FD0001, although it’s probably unnecessary.
