Coffee Time (Lots of Ads)

The game itself is a puzzle I like, but there are just too many ads, and many of them are long, which is tough. The first few levels are a trial, and if you want to play more, you have to buy it, so it's basically a paid app. Yet, the rewards are small and the duration is short. The time quest is a generous 15 minutes, and the initial reward was decent, but it's already down to 200 gems. With recent reward trends, it might become expensive again soon. I tried hard, but I couldn't complete the hidden quest for watching ads X times before the period ended. If there were that many ads in a short time, I felt like I could clear it, but maybe it wasn't enough. If I could at least see the progress, I'd think 'Just a few more tries!' and keep going. I think the game content itself is really good, but There are so many ads that I don't even have the energy to talk about the game content. Because there are too many ads, I can't clear it, so I keep playing the same problems over and over. It's only kind that there's no hidden quest for 'Level X Clear'.
