This game has some functions that were on the original plus some more I have added
- '1' or 'R' will Restart current screen again. Usefull when you get to a dead end position
- '2' will PAUSE the game. Any key to continue
- 'H' will Restart the game from the very first screen of the game
- '4' will step to next level/screen

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