The script clicks the cookie just first 100 times to get the game rolling. The rest is done only by buying upgrades in a relatively efficient way. Maybe it is not 100% mathematically the most efficient player, but much smarter than average cookie clickerer :DDD I challenge you to beat this script by only buying upgrades.
