waaah... math is hard, therefore I hate this game. diff b/w L1 and L2 is addition to multiplication and recognizing factors of 2, 3, and 5. you guys are idiots
I like this game a lot, but agree that there could be better controls. hot keys!! the ability to grab joints and move them, also its difficult to get bridge piece to their exact max length. DEVELOPER: check out 'Fantastic Contraption'
