Prototype of Pac-Man game in WebXR (mixed reality). Built using Three.js.
Place the game on any flat horizontal surface. You can then move around the game in 3D (move closer/further, rotate around the game).

Because of the current restrictions of WebXR, the gameplay is not as clear as I'd like.
To move Pacman up/down/left/right, you need to touch your phone's screen at certain coordinates:
