Too simple!
It has potential, but it's currently simply too simple. You should also give credit to the musician. That music was used in so many Flash games that I think it's kind of boring. It's a bad loop, anyway. Too short.
You should try adding variations to the click challenges. A few ideas come to mind. You could make the button move. You could also add sound effects and have an invisible button hidden somewhere on the screen. You could say "Find the button and click it as many times as you can!"
