interesting idea. kind of meaningless if you regain your limbs next level. It's a bit slow to remove limbs after the initial joy of the idea has worn off. don't get me wrong I love the idea, I have never seen it before, just think it's got a few steps before reaching the brilliant level.
I loved playing the incredible machine games, this is just as good. Not sure if there are multiple solutions to any one puzzle like the incredible machine but that doesn't really detract from the overall fun of this.
