I made a few NES style things before but this here´s literally something that will work in NES Super Mario Bros. 2 100%, I know cause I actually tried it, and it was incredibly fun and lucid or surreal to see myself invade a game for the first time.

I was back and forth so a few changes might no be reflected here and theres a few things to look out for, like the walking bounce being added by the engine itself, but it´s basically all the sprites I made and can be added with tile editors and the Hex color codes.
