You are true BBC connoisseur! Nobody else would know that i added on some extra levels for variety!. Moon level ia delibrately different to break up the rhyyhm of play. Difficulty is so hard to judge and I didnt want to make the game too hard. I have completed all levels in testing! And you have the added strategy of trying to build uo your stops (not in the original) through good, courageous and lucky play. Thanks for your kind words.
