I am planning on making a new one in the future, though it'd be called Scooby Horror: Arcade. It'll feature multiple randomly generated levels and monsters from the show. I'm hoping to make it sometime this year or next year.
I don't plan on making that game or many more parody games for that matter. If I do, it'll be from the ones I have left over on my list. Getting kind of tired of them. I'm enjoying my original games a lot more to be honest.
