Is there a xbox game disc for Castle Miner Z?

I don't know where to look on my xbox 360 apps for Castle Miner Z. Would I look at browse games or something? But before that would anybody know if gamestop or some website actually has Caslte Minerz on an actually game disc, like minecraft? Also can you play split screen on the game. And would there be creative mode like minecraft? But if there's no game disc then where would I look for the full game on xbox live, please be detailed cause I don't fully understand this new xbox update yet.
