I find it hard to believe that anyone can play this game without needing some help. The fact is, there are so many points where you'll probably get stumped, one because of the horrible map you use in the game. Also, it's because of how you're expected to piece things together. I can see the latter being more possible if the map was easier to use.

Here two walkthroughs I highly recommend if you need help, get stuck, or want to play the game through while retrieving everything. I stuck a by my preferred one. Thank you to the contributors at GameFAQs.
