Just finished Mind: Path to Thalamus. Some quick impressions:
At its heart, it's a puzzle game with two main mechanics: walk around, and move balls that activate things (or most of the time, have the environment and its changes move balls for you,) then walk around some more to new places that the activated things open up, until you hit goals in the form of portals or mirrors. Is that overly simplistic? Perhaps. Is the game? Mmmmmsort of. There is a story, in a sense, of a man's quest for redemption, but it feels like it's not entirely serious and the developers are just fucking with you or feel like they HAVE to tell a story to make the game more compelling. In one sense, the way the story is told gives some explanation as to why the unrealistic nature of the puzzles still "works." But you could probably safely ignore the story and just play with the balls.
Graphically, is it pretty? You bet. Is the music and sound good? Yes, although "leaves rustling" sounds a lot like "rain" which might confuse you for a bit since rain is a puzzle feature. Are the puzzles good? Mostly, although it's FAR too reliant on timing. There was one area I screwed up several times - you have to be fast and in my haste I threw the ball too far to the right or left and missed the target - and had to trek quite a long way to reset everything to try and get it right (okay, over the two rivers, place the ball against this wall, back over the two rivers, roll this ball and hope you don't screw it up agDAMN IT!) I was expecting something a bit more relaxing than "do this and now RUN!"
The verdict: Do I recommend it? If you like timing puzzles, then sure, get it without hesitation. If you like puzzle games but aren't a big fan of timing, it might still be worth your while. If you're looking for a calm journey or an arty experience, you might feel a bit betrayed by this game. I can see how this game isn't for everyone. I thought it was alright, personally.
