Badgers Rock is a small, completely free (no ads) Windows Phone game I created using the XNA framework during the autumn of 2011.
You can find it on the Windows Phone Marketplace and on Facebook.The latest released version (V1.4) has both an online high score and cool retro sound.There was a contest arranged by the “Windows Phone Sweden” Facebook page, that ended on February 3, 2012, and the Winner Niklas Dahlman successfully completed all thirty levels with “three stars” on each levels. Not an easy task considering some levels are really hard and time-demanding to complete. He won a Nokia Bluetooth Stereo Headset BH-111. Congratulations!
The online highscore is provided and hosted by http://mogade.com/. It is free, open source and have a very easy API to integrate. You can choose to host your data yourself or let them do it for you. Really nice.
