From the developer:
""Land your lunar module on the moon with Moonshot. Use your horizontal thrusters and main engine thrust to negociate a rocky terrain. Landing sites which are more difficult are worth more points. You have a limited fuel supply so watch your fuel guage! Your score is based on the degree of difficulty, how softly you land, and how much fuel you have remaining. Dodge the optional meteors for even more points! A practice mode allows you unlimited fuel so that you can get your landings down pat. Velocity meters show you what your spacecraft is doing.
""An options menu allows you to turn features on or off such as meteors, sounds, and an auto zoom feature which automatically zooms in on your spacecraft and landing pad when you are on final approach. Moonshot also features top ten score keeping and a demo option which shows a landing. There is also a help section with lots of tips for making good landings and an option for printing the help section.""
Note: The unregistered version contains 3 ships and 1 landing site. The registered version contains 6 ships and 5 landing sites.
