I really enjoyed this game - a TON of HO scenes, ok story and graphics...I just had a lot of fun playing it. In each scene, you find one lightning bolt (for hints which accumulate...) and 2 swift birds (? - is that what they're called?). Collecting the birds will unlock the unlimited HO option. There are puzzles that were pretty easy and if you have any trouble or just don't want to do them, you can skip them. Once you find most of the objects listed, you use items in your inventory to find the rest. This is usually fairly simple to figure out what you need to do. I never got stuck - there were a couple times I had to go back to a scene I thought I was done with but wasn't. Fun game if you like HO games.
