What about a timer?

Hi! Im Levi and i want to talk about a new feature
What if i make a TIMER?

This is an infinite runner, or infinite "shooter" game. So what if i add a timer to start speedrunning it or something? Like who can live the most time. I know that there is only one enemy per 3 seconds but im sure i can make it so in every minute survived the enemy spawning speed will be like 0.5% less and if its 1 enemy / 0.5 seconds if will only do -0.05 seconds every minute. What do you think?
