Thanks to your comment, I just discovered that there is already a second installment of this game. Once I finish this one, I'm going to try it out to see where they went wrong, but you're right in saying that this first installment is a masterpiece in every sense, and I feel that it's very intuitive in terms of puzzles, allowing you to really progress. I'm really enjoying this game...
