It's a clue book that offers a detailed pictorial walkthrough of your current level. The spider shooting game is there to prevent 'lazy peeking'.
I would definitely recommend using the walkthrough as little as possible
I take a screen shot now so that if I have to go back and look I don't have to play the game again, for that area.
Alternatively, you can find screenshots of all the walkthrough pages on
this website. Saves time.
[Mod Comment: That site is gone. But all the walkthrough screenshots are here on this forum.]Is there some trick to winning the game? We never get past the first spider or two.
Not sure if it can be considered a trick, but using the arrow keys and space bar instead of the mouse makes beating the spider game a lot easier.
