I don't mind watching ads so the game company would have some income, but some ads can't be closed without players clicking through the ads. Some stages over 1700 are ridiculously difficult to complete even with boosters. I'll stop spending and just use up all my boosters and coins and then quit if this continues to happen. I don't mind pay-to-play to have some fun, but if game companies are being too greedy they'll get nothing from me.
