About 60 seconds into the demo, I knew I had to have it. The biggest challenge to this game is thinking, and you do, in fact, have to do a lot of that!
I love the silence of this game, i.e., no speaking, barely any written words. The music adds a nice ambiance to the silence. I love the surprises. I don't find it frustrating to have to follow my own dots. And I don't find it boring to use logic, even if that logic is a bit illogical.
One of the things I love the most is being able to play with the butterflies. Place your cursor just beneath any of the butterflies flutterbying about and see what happens. It adds no benefit to the game, but is a guaranteed smile moment.
I agree with many of the other reviews... it is good to be forced to think for oneself. We too often take the easy way out. I'm glad we are being given a chance to do something for our mind as well as our funny bone.
Give this an honest try. If you let go of all your preconceptions on how these games we love so much should be played, you might surprise yourself with this one.
