this is part of the problem imo. the people working for Frontier are some of the best educated/clever people in the UK. It shows in the game. BUT that is also a problem. A puzzle that might make perfect sense to them, might seem easy, isn't for the other 99% of us.
Frontier, when designing puzzles in future, keep the following in mind: Imagine the people in the Rovers Return solving it. If you can't imagine them solving it, then it's probably not solvable by mere mortals.
