Développement
Portal is Valve's professionally-developed spiritual successor to the freeware Narbacular Drop, the 2005 independent game released by students of the DigiPen; the original Drop team were employed at Valve. Certain elements, like the orange/blue system of identifying the two different portal ends a player can have open at a time (one connecting to the other), have been retained. The key difference in the signature portal mechanic between the two games is that in Narbacular Drop the player can place a portal on a wall visible through another portal, whereas in Portal, the HPD cannot fire a portal shot through a portal; however, the HPD can fire a portal shot while the player is standing in a portal.
