Wow, I was really blown away by this demo. The controls are amazing- it just feels so freaking good to play, and it's shockingly intuitive. It's made up entirely of small challenges- successfully making a jump, sliding under something with perfect timing, pulling of a roll to keep momentum...
And the animations on the disarms are so satisfying. While playing it I didn't see that many alternate routes, but watching some of these youtube vids it's clear the game actually has a lot of options for how you move around certain parts of the world.
I'm still not sure if it's a $60 purchase for me- it seems like a short game, and also one that is likely to see a price drop in not too long. But I'm really impressed with the execution, and I find myself thinking about it when I'm not playing it, and trying to climb over everything when playing other games.
