Portal: The Flash Version
A free flash game inspired by Valve's Portal. This fan-developed game has the same mechanisms, objects and themes as the original Portal, but is in 2D and has a male protagonist. Portal: The Flash Version began as a Flash project by Hen Mazolski and Ido Tal when Valve first announced Portal. This could be the reason why this Flash game and the objects it contains (such as the crusher) are more similar to the objects in the trailer than those in the published game.
