This was originally made for @Triangle5820's contest. But it didn't get in due to being based on 3D World which isn't retro. So, I quickly made another version, under the name of Super Mario World NES.
I remember having this idea all the way back in 2021. Time flies. Development began in 2022 when the contest began. I will eventually share Unfinished SMW NES as soon as I fix the bug of unable to jump.
