The game can be run from FLOP reader, DOS or QMEG menu.
This is a single player game and is controlled with a single joystick. However, one of the functions is only available via the keyboard.
From the title screen, the game is started with the START key.
The focal point of the game is a spaceship (saucer) with the inscription "UFON". This is controlled by the player with the joystick: up and down to rise or fall; right and left to accelerate or decelerate.
The only purpose is to fly as far as possible. The distance can be read from the Score (bottom left), which increases steadily as you fly.
By default, the ship flies to the left. However, the "Q" and "W" keys can be used to switch the direction of flight.
The range of the ship is limited by energy. Its status can be monitored using the Energo Box value on the bottom right. It is 12000 at the beginning of the game and decreases rather quickly.
Energy can be replenished in flight (similar to River Raid) from "boxes" that move through space. The intention is not to avoid them, but rather to touch them for as long as possible.
The game ends when the Energo Box value drops to zero. A new game can be started with the Start key.
