THE BONUS STAGE:
In order to get the bonus stage, find the key item in each level, the key item is written in the lower right corner. The key item is not “differentiated” so it exists in both picture. But after you guess it, it would become difference item the next time you play the level. Hope this clarify some confusion about the bonus stage. And we apologize for not clear enough about it :). Enjoy the game.
