Fairly inventive
While I'm not the biggest fan of these "find the difference" games they are still fun to play. The cool thing is that the artwork surrounding them is so good. You truly get the sense of being in the moonlight and having those shadows around you. My only problem is that it does get pretty hard. These have to be admired for the painstaking amount of detail it took to create them. The ones you solve at first are the most obvious.
The music is very good and creates a real sense of subtleness. It makes me glad that people put so much time and effort into this. It reminds me of those old things in kid's magazines that were like this. It's interesting to know that games like that can be played at a more sophisticated level. It's also nice to include a story.
