Super Mario Bros: Odyssey (Chapter 1)

Super Mario Bros Odyssey Ch.1 is an unofficial fan game which is a retelling of the very first Super Mario Bros game, with cutscenes, new sprites, original levels, unlockable skin-sets and levels, and a few characters and items from future Mario games. It has nothing to do with later released Super Mario Odyssey official game, it was released years before Super Mario Odyssey started development.
