LOLZ I know! Half of the combos didn't make any sense! The beginning is fun though, because you can make so much from so little and you get exited. But towards the end you will probably need the light-bulb hints. Like me!
It's a shame that nearly half of the elements are human-made, and still considered 'elements'. How could anyone agree that 'energy' and 'stone' are the same as 'skyscrapper' or 'alcoholic'? But besides that, it's a marvelous game.
I has a few problems like Hydraulic said, but it's a great game However, at 85, 90 elements, you find yourself a bit stucked: few thing missing, too many elements and too many REAL combinations that are not there in the game
