I am on level 59 (I think the final one-not sure). I can begin but you run out materials and there is nowhere to go. So this level has me totally stumped. It's fun and challenging but you need good eyesight. Mine's not as good as it used to be. I have had to play each level more than once. But I eventually figured them out. There are a few glitches. But if you can't do something and it is in inventory, it is because you need something else also. The biggest complaint I have is what are the artifacts and where do you find them? I stopped looking for them.
