When a ninja or a fat man dies, press the jump button intensively (to ensure that the last person dies), that is, boxing+timeout. After that, although the jump was successful, because of death, the system naturally played the music "We are all extinct" and ended the game. At this point, the game restarts, and you can choose Ninja or Fat Man in the selection menu (whoever dies last can choose who), but note that the visible figure in the selection menu is still Bill, but although the corresponding position of Ninja and Fat Man is a shadow cursor, you can move the selection.

It's simple. Just try it.

Press and hold the A key and the B key in the game, then press the Start key, and then release it. The physical strength can be charged to 12 at any time.

Unlimited use.

Jump off: press and hold the START key in the game, and then press the A key to select the next level.
