Nothing special here at all.
Graphics: A cutup NG logo and a blue background. Meh.
Sound: At least you went as far as to include a loop.
Gameplay: Flash jigsaws have been done before, but this is particularly bad. The pieces are too small to work with. Most importantly there isn't a "piece locking" system or anything really for that matter. just a bad drag 'n' drop that might as well be a dess-up game.
Overall: Just a poor game. Try harder next time.
