A test chamber, a portal gun, and a computer voice promising you cake you will never taste.

On gut feeling, the community places it rather low, but on still few direct votes, so caution. The detail draws a measured profile. What stands out on top: the wish to rediscover it for the first time and the soundtrack, both well placed. Fun and the desert island pick hover around average. On the other hand, attachment, controller feel, and especially art style stay low. No surprise for a 2007 title, short and a touch austere visually, which was worth it above all for its genius idea and its surprise.

Next to other puzzle games, it literally invented a concept the whole industry copied. Its influence far outlasts its short length.

So, who is it for? For you if you like clever ideas, deadpan humor, and puzzles that make your brain click. Much less if the game's age, brevity, or austerity puts you off.
