Use the arrow keys to move and jump (left, right, up). Use the spacebar to shoot fire (if you have the fireflower powerup). Your goal is to head to the right of the screen (except in the Tower level or as otherwise indicated). You can press the R key to reset Mario's position if you get stuck. This game uses the same system of taking damage as found in New Super Mario Bros. games (Fire Power ==> Big Mario ==> Small Mario ==> Lose a Life). This game allows you to play 7 original levels: World 1-1, World 1-2, World 1-3, World 1-Tower, World 1-4 or 1-5 (split paths), World 1-6, and World 1-Castle. Each level is 5 "screens" long. World 1 is not complete as I have not created the castle boss fight yet. I have not created any levels past World 1 yet either. There are 2 secret exits: one in World 1-2 and one in World 1-5. Note that the World 1-Cannon is not complete, as World 5 is not created yet. Also, note that the red mushroom platforms in World 1-4, as well as the unhappy cloud platforms in World 1-5, are dangerous and you will take damage if you hit one of them.
This game is a work-in-progress. Let me know in the comments what changes/improvements you think I should make if I decide to make a full game out of this. Credit goes to Nintendo for originally creating the sprites, sounds, and images that I modeled this game off of. Also, credit goes to RHY3756547 for creating the "Perfect Platformer Base" that I remixed to create this game. You can check out that project here: https://scratch.mit.edu/projects/845502/
