Too many LONG ads. I understand the needs for ads. There were no ads for about the first 10 levels, then there what seemed like 5 second ads after every few levels...ok, that's fine. But then there were long unskippable ads about every other level. 30 second ads and 30 seconds of play?? No way! It's like the developers mindset was "Pay $2.99 or don't play at all" I opted for the latter and uninstalled this annoying method of "forced" payment.
