It took me the best part of Monday, and bits of Sunday, Tuesday (with apologies to atreic who was visiting (Yay! Castle, sorbet, games, etc.)) and today to complete. But completed it was, and people didn't get horribly lost or despondant (or at least, I didn't notice them doing it), did different routes to collect points (which was something that I was designing for), and not only didn't lynch me, but generally complemented me about it.
Maybe now I can stop worrying about it, and start worrying about all the other things I haven't done due to prioritising this over them ;)
