Drag two of the same rocks/minerals together to create a new one. There are currently 15 different stones. You can't click the upgrades, you have to press the button [x] / [v] on your keyboard. so it doesn't work on mobile devices yet. Hold [m] to show boring debugging stuff. The order of the stones is just one I liked
The game isn't done, and probably never will be. I don't have a name for the game yet. The music is from the mobile game "Idle Miner Tycoon". all the art and code is made by me.
