the chase takes place in corridors that users wander through as the users run, they create tunnels and spaces that start intersecting with each other. bigger spaces are called chambers. These chambers connect with each other through tunnels and also when they intersect. users can play tricks in each other. A bucket of water is left on top of the tunnel entrance so it falls when the other user comes out. But we need to think how to generate tunnels as the users move though them. We need to think on how to create, maybe modular chambers that have premade holes for the tunnels to connect them or even to have them intersect with each other. but dynamically creating the chambers with holes and tunnels seem may be hard in terms of processing. we want to make the tunnels interesting as the users create them. But users tend to move in straight lines. We are thinking of creating a curved pattern for each user that will make them dig interesting tunnels in which they would not see each other so easily as if they were straight lines. a different way of creating the tunnels may be to place rocks in a grid that the users can delete as they move though it. all what the users would see as they dig the tunnels would be the rocks in front of them so it is important to make the point of view include some distorted peripheral vision to create depthin the space the small creature would have a creeping motion the big creature would move forward in a sweeping motion. a possible third creature that runs away the small creature but pursues the big one would have a massive creeping motion. one way the creatures may perceive the chambers is by placing a light inside if them that make the rocks transluscent as they are approached we could create a movable three dimensional map of the paths taken as the users move through space. we would need thee different kinds of rock at least to create some visual variations and patterns when users move.
