(Source: The Mushroom Kingdom) Level Differences World 4-1Īlthough an additional Mushroom object has been added to the level (to the left of the first Potion), collecting one will cause the other to disappear, as Nintendo mistakenly set both as the first Mushroom (object ID 2B). Wart takes 4 vegetables to defeat instead of 6.The final game waits until the egg or fireball actually appears. The sound that plays when Birdo shoots eggs or fireballs starts immediately after they open their mouth, similarly to Doki Doki Panic.(The implementation of this sprite in the final version led to a somewhat amusing oversight: re-entering a Key room while still holding the Key will activate the idle sprite again, causing two Phantos to chase you.) All Phantos seen in Key rooms are static background objects the enemy sprite is not actually spawned until you leave the room. The 'idle' Phanto sprite is not implemented yet.

This earlier behavior was actually restored in later ports of the game, starting with Super Mario All-Stars, likely to help reduce the game's difficulty.

The prototype allows you to choose a new character after dying, whereas the final game forces you to finish a level using whichever character you initially chose.

Luigi's jump animation is the same speed as his running animation.

The height at which each character carries items was adjusted in the final to better match the new character sprites.
