I've been watching the development of this game for quite a while (through slashdot articles). The final version of the game has been release and I jumped on the download. I was not disappointed. This is a really cool game.
It is in the spirit of one of my all time favorite games "The Incredible Machine" but it is infinitely more nifty. I can't wait for my kids to wake up to show them this! In the mean time I'll familiarize myself with it more...you know... so I can help them out.
