IGN just reviewed Gray Matter. Closing comments: (7.5/10)
"For all its excellent visual flair, interesting characters, and creative storytelling, the fact Gray Matter’s puzzles are one of its less impressive aspects is a major disappointment. The creative magic trick conundrums are an interesting touch, and the challenges do get more elaborate further along in the game, but many of the puzzles just aren’t that enjoyable. Even so, Gray Matter’s winding story and masterful presentation captivate enough to hold everything together, particularly as the tale reaches its bizarre climax in the final chapters."

I really missed Jane Jensen's games - I enjoyed the hell outta Gabriel Knight (they should make another) and Phantasmagoria (first live action FMV adventure game!).. Looking forward to checking this one out in the near future.
