Absolutely love this game! I recommend making a one time small purchase to rid yourself of ads. You'll find that it'll actually be worth small $1-$2 purchases periodically as well. This is the ONLY microgame I would ever make a purchase on or recommend making a purchase. The reason for my recommendation is the mere pleasure of playing this game as well as the ability to have long term progress without the need for excessive purchases. This truly is a microgame worthy of whatever you put into it.
