Really neat! I love the story-book art-style and your choice of colors was great too. Definitely was not expecting the ending as well. I'll admit, the puzzles took me quite a bit of time. I don't know why but the chemistry book just wasn't clicking for me for quite some time. It also took me a minute to find the last foghorn combination but that was because I was expecting to have to pick up the picture I just finished again. I really liked the picture puzzles too, very unique shapes and just enough hints in the artwork to get you started in a direction.
