Portal Orange I

Portals in a pair act as a direct link between one another. Anything that goes into one portal comes instantly out the other. Objects going at high speed into a portal (such as falling into one from great height) will maintain their speed when coming out of the other, giving the player the ability to launch themselves or other objects through the air. Portals are also capable of continuing any sort of beam, specifically the Excursion Funnels, Thermal Discouragement Beams, and Hard Light Bridges. If only one portal in a pair exists at the moment, the existing portal is an oval completely filled in with color. When attempting to enter an unpaired portal, it will act as a solid wall. When both portals in a pair exist, they will appear to be like windows. When looking through one portal, you can see directly out the other. When a portal is linked, you can identify which portal it is by looking at its colored border. What do portals and ports have in common? Would you have the courage to pass through them?
