In general I really enjoy Minmaxia's games. They tend to have very idle-friendly gameplay which is something I look for in a longer-term incrementals. It's difficult to recommend right now, but it's stuck with me, so it might stick for you too.

As has been mentioned, the pathfinding is quite wonky and is prone to getting stuck in a loop of going backwards and forwards between two objectives. The miner behaviour is a bit weird too - I would like to see more prioritisation of exploring caves (and mining ore they find) before trying to find new ore veins by digging dirt, alongside being more responsive to the behaviour you select (dig deeper / shallower). Maybe a specific "Go to depth" order.

But after the first prestige you can at least immediately get a second miner, and a third miner only a couple more prestiges after that. I didn't reach that far yet but I do think Mining Crew has potential to be quite fun as a phone or second monitor game.
