Good Idea: If I don't get it after watching it and attempting to substitute the words like you direct then it has to be a good thing...right?
Making a freeware, epically fun flash game with somewhat customizable characters, and a number of appearances among unique ones are mild knockoffs of popular characters--just shy of gimmick infringement. (I.E. a fighting RPG and characters resemble those of street fighter, KOF, final fantasy 7 thru 10, bleach, naruto, etc.)
That's right, Bixby Snyder folks.
