I've had a quick look at the site and think it's a good idea if you're having trouble getting to certain scenarios, increasing lucidty etc. The way they have created it is quite smart i think. Because once you get there you have the opportunity to use their simple objects (doors, mirror, fountain, dojo) to achieve lucid tasks/increase lucidty. At the moment I have other goals in mind when i get lucid but later on down the track I'd like to have a go to try and get there.
