One handy thing to note, is that enemies can't get you when your on a ladder. So, if a knight is coming for you, run back until you find a ladder and scale it a rung or two, then wait for the knight to pass you buy, then get off the ladder and run like the clappers to get out of the knight's patrol area before it comes back around to get you.
Oh, and if you think the knights are bad, you've got some fun surprises in store .
Hope you have fun with the game, there is a lot of stuff to unlock and new stuff is being added with every version, its one of the best audiogames we've seen for a very long time.
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
