Hewitt is a very long game, with a complex level of item interaction required to find everything and get everywhere you need. A little too complex at times. Some of the tasks you have to complete are a bit out there and require specific clues to complete, so unless you touch/examine/talk to everything, you'll probably miss a vital hint somewhere. A lot of adventure games fall victim to this common trap. I had to consult the walkthrough myself, and to be quite honest I'm not sure I could have ever made it through the game otherwise. A save feature is offered, so if you're determined to do it yourself you can always save and come back later. Also, it can be a bit cumbersome combining items, as you have to look at it, click it, move it, then hope it works out.
