My flash game has been ripped off, is there anything I can do?

Recently we launched a flash game called ball bounce. We designed this game from the groud up, the concept was 100% original and so was all the coding.

Yesterday I stumbled across this game by flash games 247. It is, for all intensive purposes exactly the same apart from a few updated graphics.

Do I have a case? Can I do anything?

Any help is much appreciated!
Thanks,
Jon
