The much-publicized 2D remake of Valve's Portal is now out, with links to binaries for Windows, Mac and Linux operating systems all available from the Cymon's Games site.

In ASCIIpOrtal you can fire up to two portals with your hand-held portal device, then enter through one before coming out of the other for some mind-bending teleportation effect. Some of the puzzles include manipulating switches using blocks, placing portals on the other side of chain links, dodging boulders before they crush you, and avoiding laser fields that will burn your flesh instantly on contact.
