Fun game at first. The problem is that the game stays off with ads for bonuses (when you want them). Once I got to around level 20, the ads increased and became involuntary - happening when you do some mundane action like collecting from the caravan. Could be a 4 or 5 star game if they kept ads optional.

I like that the game allowing usage of in game currency to improve stats but the auto exploration depends too much on water. That ran out fast. Ads is by choice to get certain currency. Maybe I'm low level that haven't see any customization on character.

I've only just started my journey but enjoying it so far, I'll be back to update as I continue exploring. So far it's a pretty decent Idle game for people who don't have a lot of time up their sleeves and don't want to spend it staring at ads.
