In this game I have added this commands
- '4' will skip to next level
- pressing 3 will move the player sprite 2 pixels up
- pressing 2 will move the player sprite 2 pixels down
Use these two last tricks *only* if you end with the sprite in a position
where you cannot move it!

As you'd remember, the V9958 engine accepts pressing Fire1
and Fire2 simultaneously to exit the game. In this case
it will be Space + N
