At first, it looks great, but the more you play, the worse it gets. There's too much fuss and opaque mechanics. There are a lot of tabs with upgrades, resources, and purchases. It's supposed to do something, but in reality, I'm just digging, collecting, and constantly dropping things. I'm constantly collecting, upgrading, and 90% of it doesn't make sense. This is a big problem for the game. When the player doesn't need most of what the game offers. Why play this game at all?
It's sad. You can see that the author tried and put effort into the game.
