This is one of the most hilariously broken games I've ever seen posted on this site. The first upgrade DOUBLES the value of a manual click, and very quickly it scales out of control and the currency gained from a click is orders of magnitude more than needed for the next doubling upgrade. You'll spin out of control almost immediately and be able to afford every unlock in the game in under a minute.

Giving it a thumbs up to encourage everyone to get their yuks in.
