pretty nice!
the graphics are simple and nice, the mouse movement is unique in a good and fun way, and the whole game itself is pretty enjoyable.
as for the actionscript, every time you click on instructions it plays the music. so you can have about 10 copies of the song running at one time. i dont really care if you fix it because the game itself will not be drastically better or worse if you do.
best of luck,
