By the way, you can usually find stuff like this with a search engine. All you need to put in is "Oddysee" (or whatever game) and "walkthrough" and you'll get a lot of usable hits.
There is also a great site called the Universal Hint System that uses layered, subtle hints, trying to give away as little as possible. If the first hint for an area or puzzle doesn't help, you can go deeper into the hints, and they give away a little more at each layer. Eventually it will give you a basic spoiler. It's great if you usually like to figure out a game on your own but you're just plain stuck.
With AO, figuring out how to deal with sligs, scrabs, bombs, paramites, mines, bats, meat saws, etc., was challenge enough, so I used this walkthrough, especially to find and keep track of all the secret areas, but with adventure games I like to try to get through them without help.
