Cold Sun Surf by AndyMakes is a dark, spaced themed game where you have to collect as much money as you can before you are sucked into the terrible dark sun. Along with the money, you need fuel as well to survive. You cannot fly if you run out of it. If your body dies, you will keep the treasures. The screen indicates a fuel tank bar and a dollar icon which tells you how much fuel is left and how much money you have collected.
