The Portal (spoiler alert)

.
I just finished a brilliant video game. It's a rather short first person game, called The Portal in which you travel through a maze filled with clever puzzles, accompanied only by a voice of some sort of a black-humored master computer (and what a brilliant sense of humor it has! :D ) that keeps promising you cake once you are done with the puzzles (you're a part of some sort of an experiment)... and by the friendly companion cube. :D

The game is full of vitty humorus observations by the computer that create a lively atmosphere, and of simply genious puzzles with even more genious solutions.

The game ends by you escaping the maze upon completion and destroying the master computer that is responsible for your imprisonment in the maze.

Once the credits role, this song comes up. It is the supposedly vanquished master computer singing some sort of a farewell song. And it is nearly as brilliant as the game. :D
