This game sucks, every time I upgrade ads just randomly pops up and after you close the ad, sometimes the money you spent to upgrade don't save which is why this is the WORST GAME EVER!!!!!! It would be so fun if there was no Ads, only few bugs that rarely activate and a good animation, although the ads are incredibly unstoppable so this is by far THE WORST GAME THAT I DOWNLOADED ON A YEAR!!!!
