I think that since your first game was stellar with good desin and a the use untouched topic and using it perfectly with lingo and jokes that gamers will get (like all the IP are belongs to us)
ussaly a first game is like a crappy maze game or a rehash of a subpare game
i have idea actully i think your second game should be like a Legend of Zelda(orginal) type game with many gameing items, enemys,places and chareters in it, and just changed the gaming refrences a little bit so the arnt infringing copyrights
But hey idrc if you make a new game tommorow or 1000 years just plz make a new one
