I just got a "perfect balance," then an instant later, it fell. (This was level 15 on inferno.) I'm glad to be closer to the badge, but the way it tells if a structure has perfect balance or not is probably a little flawed!
I don't know what I did, but I managed to fall off the boss stage with four lives left. And I kept falling and falling and falling. I ended up having to start over!
188 commands. Levels 11 and 12 very difficult though, it seemed to me level 10 should have been the last level. I really enjoyed this game though, wouldn't mind seeing more like it!
