Larger games generally feature save points as well as the ability to transport the player quickly between certain rooms on far sides of the map, eliminating tedious retracking in the latter parts of the game. Access to new abilities can also open up shortcuts that reduce travel time, as well as discover secrets that help to improve the character's abilities. For example, gaining access to double jump or wall jump abilities can give players more mobility, while obtaining the ability to transform into a smaller object can let the player slip through narrow corridors.
