Does player age have any effect on the game?

Mischief Makers is an older Nintendo 64 game from 1997.

When a player sets up a save they are asked to input a player name and the player's age. I've played the game with various different ages (01, 13, 21, 99), and have never noticed a significant difference in game play or difficulty. Is there a point to asking for the age of the player? Does the age of the player have any effect on the game at all, if it does what is that effect?

Age affects only the ending. In fact, only one screen, right before the credits.

Sooo... spoilers ! (very minor, but still one of the last images of the game - from vgmuseum.com)

If your age is 15 or less :



If your age is 16 or more :
