Dog water, your game isn't fun enough to sit through 30 sec ads every 2 minutes in order to level up ad. In order to upgrade ad. In order to proceed to the next level ad. When the drill over heats ad. Oh you want a power up ad... I wouldn't mind paying $10 to remove the ads but there's no option to remove them, stay clear of these ad hungry games, it's more of an ad then a game
