All the shapes stacked and don´t move archieve a 'perfect balance'. Think when no shapes fall in one full minute can archieve a 'nice balance' with less % points. My instable tower don´t fall and don´t estabilish on 10 minutes...
I try solv lvl 64 30~35x. One little fail movement and you lose the lvl.
I use a Walkthrough, my english is bad...low vocabulary. But I love the puzzles! 5/5
