- If life is lost, the level does not restart, and the player's
  ship appears from behind the screen with a period of
  invulnerability, as in the game Life Force.

- added the ability to continue the game after a loss by
  selecting the "continue" menu item on the title screen.

- Continue also works like an in-game save game, i.e. after GAME OVER, 
  information about the level, hi score and number of players is saved in SRAM. 
  (but only after GAME OVER, and if you reset in the middle of the game, 
  the game will not be saved.)

- At the end of the game, after the "congratulations" inscription, 
  the "bonus 100000" inscription appears as in the Japanese version and other
  inscriptions, the inscriptions also change when passing the next loops.
