Navigate Interface: Tap buttons on screen Thrust Upwards: PageUp button Thrust Sideways: Tap on screen to left or right of pod Quit/Abort Game/Exit Screen: PageDown button Pause game: Type 'p' in the graffiti window. Any action unpauses.
Your pod will be stationary at a the top center of the screen. As gravity starts to pull it down the pod will drop to the surface. You may thrust upwards by pressing the PageUp button in the center of the pilot. To thrust sideways tap to the left or right of the pod to thrust that direction. Tapping on the left side will make the left thruster activate and will make the pod start to move to the right. In order to stop sliding you will need to tap the opposite side enough times balance out the current momentum.
In order to land your fall rate must be equal to or less than 3.0 m/s. A landing with less than 1.0 m/s results in a perfectly smooth landing. Anything over that 3.0 m/s and you crash. In addition you cannot be sliding left or right any faster than 5 m/s when landing.
The bottom left of the screen has a white bar representing your current amount of fuel. Every time you thrust 1 cell of the 100 total is used up and the bar shrinks. If you run out of fuel your pod will fall helplessly downwards.
Also on the bottom is the current gravity rate. A gravity of 1.9 is the maximum the pod can start to counteract. To the very right is the current fall rate. This shows you the rate that the pod is dropping at. It must be 3.0 m/s or less for landing.
Your current score is shown on the top right of the screen. When you land successfully the score is increased. If you make it back to Earth, any unused fuel is also added to your score. The amount added is doubled if you had landed on the landing pad. At least half of your pod must be over the landing area in order for it to be considered on target.
If you fly off screen or crash your current game will be over. If your score is high enough you may be asked to enter your name. Simply use graffiti to enter the text, then press OK. Pressing cancel will enter the score with no name at all. Choosing abort will quit LEM and your score will NOT be recorded.
You may enable sounds and music. Sounds include the flying clicks, impact and thruster noise, and tap clicks. Music includes the small fanfares heard when there is a crash or successful landing or when the mission is aborted.
The landing pad width changes in increments of 5 meters and must be between 10 and 25 meters wide.
The starting gravity ranges from 0.1 m/s to 1.9 m/s in 0.1 increments.
The fuel cells can be changed in adjusments of 5 cells each from 50-100 cells for startup.
