Portal: The Flash Version

Portal: The Flash Version is - like its name - an unofficial Flash edition of the game Portal.

Without much background story the player takes control of a mysterious character in an orange jumpsuit, who is a test subject in some experiment, and a gun-like device in its hands. That device is actually the Aperture Science Handheld Portal Device (ASHPD), and it has the ability to open two portals and use them to get from one place to another.

Now the player must use the portals to his advantage and make his way through 40 rooms in order to win the grand prize - cake!

In Portal: The Flash Version the player must solve puzzles throughout the entire Aperture Science test facility using only the ASHPD and his wits. Though a very powerful device, it's not as easy as it sounds: portals can't be opened on some surfaces, no more than a pair of portals can be open at a time, and the test facility is filled with hazardous obstacles on the way, such as sentry guns, electrocuted floors and flying energy balls.
