This is a 2D pixel-style plot puzzle game with prop mechanics. Players need to use the camera to break through the obstacles and find the exit in the dream. There are no dialogues and texts in the game, and the player needs to solve the puzzles using clues in the scene.

How to play: Players can use the camera to take three photos in each dream, and can travel to the time point when the photo was taken at any time, and use this mechanism to solve the puzzle in the dream world intertwined with multiple timelines.
