ok thats very cool.
a lot harder than it looks

I couldn't get it to show me the top scores. I was pretty curious.

Highest I got last night was level 5, I think.

Pretty addictive. Now if only I could get it to stop playing that damn music. (I want to hear the little clicking noises, though, so turning down my speakers isn't the ideal solution.) All video games should have a Music Off option.

This one does. Click "options" and then click "music off."
