This was done in about 24 hours time. I was having fun with the new lighting effect they added recently and it inspired this simple twitch game.. you can see more about it here at the top of the page (as of May 2014)

I made it to submit to the //Publish/ contest Microsoft held recently. I have a newer version being pushed to mobile this weekend, but the basic game is still going to be the same, just some usability improvements and some added instructions for first time players.
Thanks!
