Yume Nikki
To beat the game, the player has to find all 24 "effects" that are hidden in Madotsuki's dreams. Effects cause a change to Madotsuki, like turning her into a witch or making her small. The player can drop them in the main dream area, where they turn into egg-like objects. When they wake up, there is a step-ladder on Madotsuki’s balcony. Walking off it makes Madotsuki jump off the building to her likely death, ending the game.
