Since you enjoying playing the 3D version of Portal so much (and if you didn’t play it, stop reading this entry right now and go play it), I wanted to make sure you knew that there was a 2D flash version as well, compliments of an article at Evil Avatar.
I haven’t played more than the first level, so I can’t attest to the overall experience, but sometimes you gotta trust in fanboys (the designers, not me).
What’s even more exciting though, is that the developers of the Flash game have released a mappack with 40 levels for the original Portal game, based on the flash games’ levels. How’s that for circular design? This gives almost 3 and and half hours of new Portal content.
I’ve gotta delve into playing the custom Portal maps that are all available now.
