Interesting...
I love Portal... easily one of the best games every created. As far as adaptations go, this wasn't the best, but it was a good attempt. The graphics weren't terrible, GLaDOS sounded great and had some funny phrases, and the gameplay wasn't the worst, but it wasn't the best. The puzzles were... odd. I wasn't sure of the entire intent of the game until I got far enough in that the little crack in the wall had a crowbar and key. Even at that point, something happened when I chose a door and died. I hit the "<< restart" and the game glitched, automatically showing me a "I'm still alive" ending. I assume that's a victory ending, but I honestly have no idea. I think if the intent of the game were cleared up... maybe a little explanation page with instructions or even just add in GLaDOS saying something about escaping near the beginning, and you'd have yourself more of a winner. Cleaning up the gameplay would be a great benefit as well. Hope to see maybe a version 2.0.
