Several hidden items can be found by attacking objects with Sayo's purification rod, and can be used to either enhance her attack or grant the player points. Once a certain number of points are gained, the player will gain another life and have an additional chance to complete a level. When all of the player's lives are exhausted, a "number match" screen appears with a random 3-digit number in 50-base increments (100, 150, 200, 250, and so on). If the last three digits of the player's total score match the number displayed, they are granted a free game; if not, the game ends.
