We're good to go; load it up and have some fun! While you're entertaining yourself putting the puzzle together, think about the different ways you could improve the project. Maybe allow the pieces to snap into place or have something exciting happen when the puzzle is solved... or better yet, think about your own creative and exciting mashup to write!
