User guide

Shoot everything that moves. Try to destroy the boss as much as possible. There is a boss timer that will auto destroy the boss but you won't get a score bonus this way.

There is always a safe area no matter how crazy the patterns are.

About Replay:

  • Only available after 1 game( doesn't matter if you loose or not) or...
  • Also available when there is a saved replay on the flashcart.
  • Not available when you return to the main menu when the game is paused.

Score should be a little higher with autobomb set to off. If all else fails, don't move!
