Community:EgoMoose/Teleportation portal demo

Teleportation portal demo is a game created by, and is the first game on Roblox to demo the use of portals (teleportation gate in which the player can see objects through it). Players can travel from an empty baseplate to the generic Crossroads map and vice versa, and can see the maps through the portal. Since the release of this game, a second version, known simply as Portal, was created which features the same portal system but much more like the Valve game Portal.
