Welcome, i'm working on android game called Underwater Miner. This is a free two dimension game which you are work as a subcontractor for a large corporation. You are a miner who sits behind the wheel of an underwater vehicle adapted to the mine of various minerals at different depths, so there are many difficulties with that. The game is about mining for minerals, selling them, and then for a gained money you can upgrade your vehicle in different ways, also you must repair your vehicle and replenish resources in base.
