Here's the latest walkthrough, Perfect Balance. It's a very entertaining skill game, where you have to stack different shapes on top of each other in a way that they are fully balanced and thus won't fall down. There are two modes, Harmony and Inferno respectively, though honestly, there isn't much difference between the two, other than the graphics, I've even found the same levels in both modes. The video tutorials are now available on YouTube for both modes (40+40 levels), please rate them if you think they've helped.
Perfect Balance Harmony Level 01-40
Perfect Balance Inferno Level 01-40
