Game balance is not good

I like merge games and play them often, but this one has bad balance. It takes too long for stamina to regenerate, and there's a limit to the rewards you can get from watching ads, so leveling up is slow. Maybe because it's a Korean company's game, Korean text occasionally appears, and since I can't read it, I don't know what it says. Etc. They're doing payment verification for events, but I didn't even feel like paying for this. I also didn't have any title quests, so I think I'll cut my losses and uninstall soon.
