Happy to watch an ad to get rewards. In that instance I'd even be happy to pay for ad free, if I was enjoying the game. Getting an ad shoved in my face at the end of every level is overkill. I spend twice as much time watching ads, as playing! I didnt even bother to use the reward booster ads, because after 11 levels I was already sick of seeing ads! Take out forced ad watching every freaking level and I'd consider playing again, since I love this sort of game.
