I like the direction this is going. (As long as John de Lance isn't replaced by the wacky anthropomorphic wombat)
It also helps to separate from big daddy Portal.
I like the look of this.
A lot like Portal, and if they polish it enough that will mean there is little to fault in it, but also doing enough different to be classified as not just a straight clone. Looks like it will be fusing Portal with Sands of time to an extent, which could be interesting...
