CONTROLS AND MECHANICS- Arrow keys or WASD. Mystery blocks can give you coins or powerups. Lives turn you into Super Mario which can crouch and has an extra life. Fire Flowers turn you into Super Mario too, but if you already are Super Mario, they turn you into Fire Mario, which can shoot fireballs using the X key, and has two extra lives. The Super Star works regardless of anything, and makes you invincible for a while. You can stomp on Goombas to destroy them, and Koopas turn into Koopa Shells that you can kick. Piranha Plants emerge from pipes. Collect the item inside the End Box to move to the next level. EDITOR- Press 0 to enter the level editor. Use the number keys to switch between tile types. Certain tiles auto arrange. This can be toggled using the Q key. If you want to layer platforms, or place two pipes next to each other while auto arranging, hold the space key. You can use E key for the eyedropper tool. Exit the editor or enter another level to save changes. LOAD AND RESET LEVELS- L to load a level. R to reset the level as a blank canvas.
CREDITS- Thanks to griffpatch for his Tile Scrolling Platformer assets, and to Nintendo for the original Super Mario Bros. 3! TOP 1 LEVEL- A level called Tartarus, really hard level (at least I think so). It's level 4.
