Forced to buy coins to continue at higher levels

Game is fun but when you run out of coins you have to watch ads which is no big deal, however or only get 1 coin per ad. When you start getting to higher levels each try is about 7+coins. So you are pretty much forced to buy coins or else you cannot continue. Also it starts you back at level 1 when you run out. Very frustrating. Otherwise game is extremely addicting.
