I was having problems solving puzzles, and was ready to give up on the game, contact the company, and demand my money back, because I was so very frustrated. I stumbled across the detailed answers to the puzzles, and that helped me tremendously.

The link can be found here: http://www.ldwforums.com/ubbthreads/ubbthreads.php/ubb/showflat/Number/25915/page/1#Post25915 but please be forewarned! This is the DETAILED answers, not the hints. If you only want the hints, click the link in laurence's post. And the only reason I'm posting the link to the detailed one here, is because the title of the post does say it's for spoilers. Otherwise, I wouldn't do it.
