Super Mario Land/Gameplay

Controls
Crouch and Slide: Super Mario and Superball Mario can "crouch and slide" by holding and  to run right, then hold  to duck into areas that were once only accessible by Small Mario. If you end up getting stuck, hold to the direction you want to get out of and tap  repeatedly.

Clearing Small Gaps: When an area has small gaps you don't need to worry about precision jumping, Mario can simply run through them. Hold, remember don't let go, be on your way and clear those gaps.

Soft Reset: During any time of gameplay you wish to start over and return to the title screen, simply press simultaneously.

Mario
Mario is the hero of this adventure and his main duty is to defeat the bad guys and save the princess. Once the game begins you start off as Small Mario, but once he gets a mushroom he gets bigger and becomes Super Mario. Super Mario has the ability to smash through blocks and crouch. Also as Super Mario you can find Flowers which make Super Mario become Superball Mario (even though he doesn't look different). As Superball Mario, he can shoot superballs that defeat enemies and collect coins. These superballs are different from fireballs commonly found in other Mario games since they don't just skip through the ground, they bounce off of the ground and walls.

Defeat: During this adventure there are many dangers that might kill Mario such as falling into bottomless pits, running out of time, or being hit by enemies. If Super or Superball Mario get hit, don't worry it's not a lost life, he shrinks back down and goes back to being Small Mario.

Marine Pop and Sky Pop
In Worlds 2-3 and 4-3 Mario is able to ride the Marine Pop or Sky Pop in their respective levels. These levels are unique to Mario games since they don't play like a platformer rather more like a Shoot 'em up.

Princess Daisy
Princess Daisy is the damsel in distress in this Mario adventure taking the place of Princess Peach (or Toadstool, whichever is better). She is the princess of Sarasaland and needs saving since she has been kidnapped by an alien named Tatanga, the Mysterious Spaceman, who wants to marry her to take over the world. As Mario goes through his adventure he will find imposters that turn out to be enemies in disguise that will have him in a wild-goose chase, sort of like the princess being in another castle stuff from Super Mario Bros..

Items
There are various items and Power-Ups Mario is able to get and aid him in his adventure.

Other
There are many other things that Mario will encounter in his adventure.
