This should be called "Ads"... when given the option to multiply your winnings by watching an ad, and you select continue instead, you STILL HAVE TO WATCH AN AD! I avoided using mid-game powerups bc I thought it would consume something. I finally tried one and it made me watch an ad in the middle of the game. Leveling up the cannons is pointless and everything else probably is too. Watch an ad to level something up that you have a small chance of using, then you have to watch an ad to use it
