The worker automatically builds to gain money, and you can buy upgrades to get more money per hit, and faster worker speed. Rebirth in order to gain more money per hit. Get an extra worker to have 2 workers at once, too make twice the money.
CAUTION!!! TOO HIGH WORKER SPEED MAY CAUSE LAG!!!!! There is currently a bug where when you buy the extra worker, the first worker animation doesn’t work. You can try to fix it by making a remix and fixing the bug.
