Wow...
What an amazing game. I really loved the art style and the dialog, and the small details you included, such as when you click on a painting. A few small problems here and there, but mostly perfect.
The main complaint I have is that there aren't any clues for some of the puzzles. I could be wrong, but the first puzzle was entirely guessing the pattern.
Other than that, though, the game really is excellent. Good job. :)
