Can't enjoy it anymore

I played this a while ago through Time Quest and really enjoyed it, so I kept it. But when I opened it again after a long time, it's become a game riddled with ads, just like many others. The daily bonus is completely unobtainable due to a bug, and there are no other ways to get helpful items. So, for difficult stages, I had to watch ads multiple times per play, use items, and even then, I couldn't clear it after many tries. Using the hourglass item didn't stop the countdown, and when I tried to get coins by watching an ad to extend playtime, I got stuck on the coin purchase screen and couldn't go back. I had no choice but to return to the title screen, only to find my coins drastically reduced. I was so fed up that I uninstalled it. It used to be a simpler, more enjoyable game. What a disappointment.
