Gem Miner is a really fun game where the object is to get as far away as you can from a mine that is not only full of dangers, but also full of jewels that you must take home with you. Your mission is to descend into the mine to search for materials and then return to the surface and sell them before your poor dwarf star falls victim to one of the hundreds of dangers that lurk in its depths. When you return to the surface, you can not only rest and regain your strength, but also sell any materials you have collected during your expedition. With the money you make, you can buy ropes, ladders and other tools to go further into the mine and survive there for longer. Gem Miner is a game of... survival, where the key is to have a good strategy in place for when you go down the mine. That is, the most important aspect of the game is to ration your energy and know exactly what to do at any given moment.
