A prototype about mining, finding gems, and buying resources to mine more gems.
The pickaxe on the game has a durability count. Each hit decreases its durability. The mined gems are used to buy more durability for the pickaxe and to buy ladders. The character can’t jump, so the only way to get back to the shops is by placing and using the ladders. Mismanagement of the ladders can leave the player stranded deep into the mine.
