Using the hint function, if you click one that moves 2 and you click the one that doesn't have the circle, it says its wrong. Also when it says to press undo it should only go back until the place you messed up, not to the beginning. Otherwise 5/5 good game
I noticed under the Energy tab only, it doesn't highlight in gray around anything, but all the other tabs do when you mouse over something (ex: upgrade buttons)
