Well that was boring....
This is vary easy game you have to use the same idea people use to build a brige you have to give your strucher suport by connecting the nodes. i find that making triangles and squares works best. you have to get the ball to not only reach the end portal but go though all the wight lines before they get there to turn on the portal. Its vary simple if you think about it but it gets really boring vary fast. By looking at the other reviews it dues not really seem like many people get it.
