Version 0.3 (beta, so please, give feedback).
This is a game and also an example of how to read/use keypress functionality from figures.
it's a tribute to Moon Lander, without any lucrative pourpouse.
The game opens a figure with the spaceship that must land on the square
avoiding hitting the land.
Use the arrows to turn the spaceship and the spacebar to fire the engine.
