This may be a "Old man shakes fist" thought but: a number clicker app should not charge $12.99 IAP. I get that we, as devs, want to have some income for our projects. $13 to turn off ads on what is really just a digital hand clicker is a bit silly. Charge $3 and be done with it.

Alright. That's all. Oh, and stay off my yard! *shakes fist*
