Timers do indeed add urgency to nearly everything in life. In computers, timers add urgency to many things as well, such as reboots and OS installs. Since we're doing scratch games, this indeed wil be very interesting to add. Since timers are used in alot of games anyways, we mine as well add some timers to our scratch games. How would I use timers in scratch games? I would reserve them for the levels that require the most skill and speed. In other words, I'd add a timer to the hardest levels of my game.
