KiiluhElaiine, the game saves progress automatically. If you've disabled saving in your flash player's preferences, or limited the size of the save file to few KBs, then it won't save.
werewolf505050, If you can balance all 9 diamonds then you've found a really good solution or then the level is too easy. :) But in Perfect Balance 3 there'll be more!
toooinx, thanks! ;) Yes, all the math is done in Actionscript 3. We use Box2D for the physics, but I've done some modifications to it to make the game more playable. And there will be more mods in Perfect Balance 3... ;)
