Lost † Game

Overview
Lost † Game is a Yume Nikki fangame made by Atami (熱海) starring Sakura (さくら).

Gameplay
Unlike most Yume Nikki fangames, Sakura is already dreaming. Exiting the barred area leads directly to the Nexus. Collecting an effect causes it to appear in the nexus.

Outside of minimal dialogue, Lost † Game is unique in its use of a Game Over system upon being captured by a chaser or otherwise trapped. To compensate for this, the player can save at any time.

Plot
Sakura seems to be trapped in a dream world full of strange creatures. The chasers, known as reapers or "death gods", can harm Sakura directly and cause a Game Over. In order to reach the ending, all 13 Symbols must be collected and placed in the coffins seen at the start of the game.
