Each quest is hidden until you select it. Spoilers-This walkthrough is full of spoilers because after all it is a walkthrough! However, the General Tips section does not have any spoilers so go ahead and start there first.
There are no spoilers in this section, just very useful information. If you're still reading and haven't just jumped in yet, I would highly recommend reading through the General Tips. Besides helping you guys out, it allowed me to take a super close look at each level before starting the game. In addition, I took lots of screenshots while playing the game and put together a map for each level. While you don't have to take advantage of all the complexities of the game, understanding how it works might make the game more enjoyable. In the process, I discovered a ton about the game that I had missed the first time through. Well, what can I say? You are embarking on a fun, challenging, time-consuming game! I wrote this walkthrough to try to add something that other walkthroughs don't have.
