So-so idle mining 1.0 game. Basic. Tech tree is very limited, with many "explorer III explorer IV explorer VII" type of unlocks. Tech unlock system is also quite linear. You must get x unlock, followed by y unlock, so you can get z unlock. It just doesn't feel rewarding or like I have very much choice/agency. It's not bad per se but I wouldn't call it compelling/super fun either. Something to do in a doctor's waiting room.
