Lander is operated by using the arrow keys, to produce thrust for your ship. Down Arrow will send you up, Left Arrow will send you right, and Right Arrow will send you left. Simulates a gravity by incrementing a delta value for y. Land on the green strips or else you will crash. Make sure you come in slow or you will find your ship in pieces.
Inspired by my old Commodore 64 Lunar Lander. I'll add more to this later.
