"Improbable Ending" is an interactive VR game. This is a first-person puzzle/maze game based on forced perspective and optical illusions. The whole world is connected by different doors, but without any logic thread. Each doorway has a hidden effect when the player enters a specific trigger, every setup in the game will give the player a sense of the unexpected feeling. Surrealist artists, especially René Magritte inspire the surreal effects with hidden layers.
