It seems like there’s a whole lot of imaginative house for a modernized model of Pac-Man dipicting the titular entity as some sort of all-devouring eldritch creature, roaming by means of huge labyrinthine areas, haunted and hunted by specters in its underinvestment quest to eat extra, extra, ever extra.
But, uh… I assume dumping Pac-Man right into a generic metroidvania is an concept, too.
