Run the game:
CALL &41D0
Then, I can't figure out how the game should be started... I randomly press keys and eventually it starts.

Game: destroy a bunch of weird aliens. This game written in assembly language has really nice graphics and makes a lot of strange noises (unless the computer is in BEEP OFF mode).

Keys:
4 : right
6 : left
ENTER : toggle between the 2 planes of the game (far/close)
SPACE : fire
