Minimal gameplay. You move your miner character to half a dozen points on the map to interact with menus. Most of what you do is click on a pile of ore while waiting to buy your next upgrade or item. In theory, you could just let it run in the background while your team mined. Unfortunately, the game locks up and crashes too often to actually do that. If you're not saving your game every 1-2 minutes, you lose progress and restart from the last savepoint.
Needing to babysit an Idle Game that closely defeats the point.
No real gameplay. No important choices or strategy regarding how to use resources. No adult content due to constant crashes and lack of progress. This is pure shovelware. 0/10. Avoid even if free.

I am amused by the simplicity of this game. Bring me your finest meats and cheeses.

Honestly, there's no plot, no learning curve, no secrets. Mine ore, sell it to hire help and get upgrades. Once you're happy with the flow of ore and don't need upgrades, trade the ore for H-scenes. When you've unlocked all the scenes for an ore group, you can watch them in sequence, in a longer animation loop. Rinse and repeat.

For the money, it a fun diversion with no complications.

I honestly wanted to give this a thumbs up, but I just can't. It's an extremely short, and not very entertaining game. I really like the art style, and the concept, but it just wasn't as good as it could've been. Can easily beat the game, and unlock absolutely everything in about 2-3 hours, and then you're basically done.
