Gem Miner

Gem Miner is a platform game which purpose is to dig to find gems and metals and sell them to make big money

You embody an old miner looking for making a fortune for retirement. You start with a hand-pick and a bag to collect gems and metals. Get as much as you can. But it isn't going to be that easy. You will have to buy upgrades with your profits to get better tools: stairs, seismic analyzers, lifts, ladders, and so on. That tools will help you out to dig deeper and to find more precious metals that will make you earn even more money. But be careful! Don't run your stamina out or you will get stuck on the depth of the mine.

You control the miner by tapping on the direction you want him to move. The same for digging: tap on the rock you want him to smash. You have a bag to keep all the stuff you collect as well as your special tools.
There are different game modes: "Main game" in which you will have to advanced through levels by collecting as much as gems and metals as you can. "Challenge mode" that contains timed challenges and many other missions that you will have to unlock.
