OK so basically I had a dream where a game came out on PC, it had very crudely drawn graphics, it was a hack-and-slash type game and it had Mario characters in it but they were all the original characters' imaginary friends kinda like a Mega Man Battle Network type situation. Anyways, this guy was the player character and his imaginary friend was Mario. During one of the missions, the yellow dude had to go to a cave and kill his nemesis which looked like a really wide trapezoid type thing which I don't remember what he looks like (his friend must have been Donkey Kong or some shit) but upon getting a hit it would take you back to the start of the mission. So after a couple of loops, this guy realized that his mission wasn't JUST to kill the trapezoid fellow, but to kill Mario as well. Only then would the mission stop looping (but by then I had to log off because the bus pulled up)
