The game can utilize the principle of non-Euclidean to design the environment and puzzles. It can combine several different spaces, and the player needs to find a way into the next space based on the clues gathered. The clue items can be physical objects.
For example, by exploring the environment, the player is given a key. But the size of the key does not match the lock. The player needs to adjust the angle of view to enlarge the size of the key to unlock the door.
