I just posted a video tutorial on how to complete the last 5 levels of the Odyssey here:

Even if you're stuck on an earlier level there should be some information that's useful for you in there.
Hope that helps!
ps. @ZamboniMan: my apologies if my previous remarks were a bit harsh/rude. Your feedback is welcome here.
