WARNING: This game is hard. If you tend to rage or you’ve had a tough day, maybe don’t play. THE BOSS IS FINISHED NOW!!! (It's a little hard, I haven't done it myself) Arrow keys to move, like any other platformer. Z to enter/exit level editor. Use slider to change tiles and mouse to place tiles.
This is unfinished, only the first world. Art and code: Me Music: 8bit remix of the NSMB title theme. Sound Effects: Nintendo
