Not enough stamina, slow progress, it's really tough for players

Hello? We absolutely don't have enough stamina. What is this game even about? There are tons of places that consume stamina, but we simply don't have enough. Everything requires stamina, and it's gone in no time. At least add a few more chances to get stamina by watching ads? Otherwise, after playing for a short while, you run out of stamina and just have to wait for it to recover. Even more absurd, it asks you to complete progress for every 2 levels within 2-3 days. It's impossible! If I were playing a shooter, maybe, but this isn't that. It's not that I don't want to play, but this kind of progression really makes you feel powerless. Games can have challenges, but you should be able to play them, right? Please improve the stamina system. Others have 10000 gems at level 20, my level 20 is a joke.
