I appreciate that someone made a real game from all those misleading ads that advertised a game like this but in reality were something completely different. That said, I'm all the way to level 80 and the difficulty hasn't increased at all, making the game rather boring. Worse still, I probably would've gotten a lot farther a lot faster but the experience is very choppy, not smooth. Even after paying for no ads, I'm constantly bombarded with "would you like to watch a video to get more coins?" requests, and I can't immediately say no, I have to wait a few seconds before the no option appears. A few seconds is not much, but with 3 such requests after and between levels, it gets old fast, especially if the game does little to hold my attention. I think basically they want you to pay for ad free and then they already have your money so they do not care if they hold your attention for long after.
