mode revealed some levels that were not available on the final release, including a desert stage, an underwater stage and a few others. Mega Mushrooms were also originally intended to be red. This feature is removed possibly because the designers wanted a power-up that can be obtained from a ? Block, however it survives in Vs. Then when the player Ground Pounds on the shell, the player gets in the shell and becomes Shell Mario. In another image, it’s possible to obtain the Blue Shell by first defeating a Blue Koopa Troopa. Spindrift was also supposed to be in the game, but got replaced by the blue spinning platforms in World 1-3 and other levels.
There also was an underwater stage which also featured Manta Ray in VS. There were originally three item reserve spots rather than one. Interestingly, an illustration of beta map icons still exists as a screenshot on page twelve of the final game’s manual. There was also supposed to be a Mario and Luigi co-op mode at a time.
(It is possible that other enemies were to be compatible with this situation, too, considering the giant enemies like Super Dry Bones and Super Piranha Plant that remain in the game in generic, already-large forms.) Also, during early stages of production, Mega Goombas were going to be a generic species (the result of a Goomba colliding with a Super Mushroom and powering up) rather than an individual boss. The working beta title for this game was Super Mario Bros.
