Once you reach level 160+ a constant stupid "4.99" ad pops up just as you go to hit play on the game. It CONSTANTLY pops up and is stupidly annoying. And the game refuses to advance you unless you purchase it. Im not paying $5 for a silly game thats advertised as free to begin with. Uninstalling bc its just not worth accidently hitting the ad and being charged when I dont want to make the stupid purchase to begin with.
