At the mechanical level, this game has everything I want or expect from a jigsaw puzzle game.  Nothing more, nothing less.  No complaints.

The story is fairly weak on its own, but within the context of the game, it's more than good enough.  I like that there is a story at all to tie the pictures together, but at the same time, I don't play jigsaw puzzles for the plot, so it doesn't need to be a good story.  No complaints.

The pictures are pretty, but not amazing.  On their own, they're OK, but in the context of a jigsaw puzzle game, they're actually kind of weak.  I can't help comparing the artwork to the few physical jigsaw puzzles I've bought, which have art that actually is amazing.

The strong point of the game is the animation.  Putting together an animated jigsaw puzzles is actually an amazing experience far beyond what's possible in physical jigsaw puzzles.  My only complaint is that there isn't more of it.
