User blog comment:NOBODY/Play Fluffball - a Nitrome game that was NEVER released!/@comment-5216056-20130813210446/@comment-24682750-20130813223802

Actually what appears to be something rather tough is that you've got to collect many gems to unlock all of the levels. It is quite odd that they did not actually released it, I had personally thought that this game had not been finished and randomly cancelled, however, now that it appears to have been fully developed I could not find a reason of why wouldn't Nitrome release it.
