I concur, some of the puzzles were a bit too abstract for my brain. BUT, this game had a great plot, awesome music, and great look. I enjoyed it a lot.
P.S. At the same time the puzzles were unique, and I don't want to in any way discourage out of the box thinking when it comes to puzzles. You did the right thing by starting off with a simpler puzzle (the dolls) and then did a progression. I see that now, but at the time I couldn't quite catch on to it.
