Take all that was good from Portal (a.k.a. the great portal physics). Add some cool new ways to make your head hurt (bridges, gels and ramps), and mix in with some actual back story. The result? The best game of the last 10 years.

This was a triumph. What else is there to say? It's a great concept, it's got great puzzles, and the price is ridiculous. If you haven't got it yet, do get it.

I bought this one along the other two Double Fine games, and had the least expectations for this. How wrong I was, as this is clearly the best of them (yes, even better than Psychonauts). True, it's a bit short, but it delivers a great experience in the 8+ hours it takes to complete. And for what it costs, it's certainly a great deal.
