I'm actually surprised people so vehemently dislikes this. While a click-less interface may not be inherently superior to one with clicks it's still an interesting concept to explore, which is exactly what Dontclick.it does.

I personally found the site to be intuitive; although, Areas, a click-less shooter (http://www.kongregate.com/games/Ridiculous/areas), did a fine job of teaching me to inhibit my urge to click everything.
