Non-Euclidean game worlds

Code Parade (also on itch.io) is developing a "hyperbolic" 3D game engine (download) where a line is not necessarily the shortest path between two places. I was impressed by the tunnels that are longer inside than outside, but the three-roomed house blew my mind. Can't wait for the unsettling haunted-house games to come.

See if you notice anything suspicious as I walk through it.Did you catch it?This four-room house actually only has three rooms, red, green, and blue.This demo surprised me a lot because I originally thought it would be super jarringbut actually everyone I show this to doesn't notice it at all unless I tell them that something is off.I guess our brains just aren't used to thinking this way.
