Although there was only a demo version available, I must say, this is something I've never seen before. It is devoted for the player to use imagination and the basic concept is to write verbs in the command line while the picture in the middle of the screen shows you how the progress, and the "inner voice" of some kind replies to your commands. Basically you have to find a logically outlined and fully constructed way of searching and finding....hell knows what. That's the gist of the full version. But as for the demo (not less interesting and, although time consuming) you have to face some challenges for your intelect and creativity of thought. Try it, its really good.
P.S.
Sorry I don't have the link but I urge you find it in Download.com and play it straight away!!!!!!!
