Whenever you're hot, you need to cool off. So whenever he's hot, press the cool button to cool him off. Burn speed is the amount of seconds it takes for him to get burned a bit more. It stops at 1 second. Every 50 times the cool button is pressed, the burn speed goes down .5 seconds. It tells you how many more cools until the burn speed goes faster.
Just a random idea I had during school. I dunno. :P Should I make a time shop? Where you could use your time to buy shades or a hat or something.
