Rainbow Islands Extra

In the option menu, choose number of lives and select ‘0’. Then you can start your game normally. When you died, instead of Game Over, you get a lot of extra lives like ??, ?! and other symbols in pair as your number of lives. However, it is not really unlimited. After you died a lot of times (about 400 times), your number of lives became 99, and when it reached 0, the game is over.
