I'm here to try and help you get past some of those rather irritating later levels in Shapeshifter. For those who haven't played this interesting (but at times deeply frustrating) puzzle game, it simply involves placing pieces on a board which "flips" the signs on the board. If you end a level with all the correct signs, you move on to the next level. Sound easy? Well, with only a little brainache it's not too bad at first!
