Not bad, but two serious issues - one, no way to adjust or mute that music. And two, no way to remove a bead once you've placed it if you've changed your mind.
Hi Robotkarateman, thanks for taking the time to review my game! As for "correcting wrong choices": as long as you haven't clicked on the "Check" button, you can correct your choice by putting a new bead onto the "wrong" one. Have fun!
