The Impossible Crypt

The Impossible Crypt is a game prototype to test the use of Impossible Spaces for VR Dungeon Crawling on the Oculus Quest using only real physical locomotion.

Note that this is a very early prototype. There is no game-play or objective yet and you can only walk around the simple generated dungeon.

The game uses a tile-based generation algorithm to create overlapping dungeon layouts in a limit space. For the algorithm to work properly you need at least 2.5m x 2.5m of free space (better are >= 3.5m x 3.5m). 

The reconfiguration of the space is hidden by a lantern that has a limited illumination radius. This allows to explore a large area by walking only inside a fixed limited space.  It can generate the illusion of actually walking a long distance in a fantasy dungeon. 

The main inspiration for this comes from the 2013 paper Flexible Spaces: https://www.ims.tuwien.ac.at/projects/flexible-spaces and also from the amazing work done by Void Room in Tea for God: https://void-room.itch.io/tea-for-god.
