Uhh... What a strange question. If you're asking "is everybody on this site super excited about playing this game and think it's the best plot to a CYS game they've ever heard?" the answer is probably no. This doesn't sound like the plot to an epic game that will be praised as one of the best games on the site, it sounds like the plot to a game that will be about 30 pages long and have a rating of between 3 and 4 at best. Doesn't mean you should stop writing it.
People don't make games based on what other people want to read about, they make games because they enjoy it. If, for whatever reason, you're having loads of fun writing this story about Kirby in minecraft land, then knock yourself out. If you're bored of it already (which I'm guessing you are since you're asking people whether or not you should finish it) then scrap the idea and write something that's going to hold your interest for more than ten minutes.
