It's a really nice experience! I didn't encounter any bugs, and the artwork works well for the puzzle, it's detailed and has a lot of interest, and has variation enough that it's challenging. It took me a little over 7 minutes to finish the assembly and I appreciate the names of the pieces. One thing I might add is a way to return to the finished artwork from the gallery, to see the image without the jigsaw lines. But otherwise it's really nice overall, the music and audio effects are good too.
