Super Mario Run is an automatic runner platformer game for mobile devices. In the game, Mario is constantly moving to the right and the player can make him jump by tapping the screen. The game features four modes: World Tour, the main game mode where players go through 6 different worlds to rescue Princess Peach; Kingdom Builder, where players can customize their own kingdom with different objects; Toad Rally, a battle mode where players can race against another player's time; and Remix 10, where the player has to play through a series of 10 short courses multiple times as part of a quest to rescue Princess Daisy. Nintendo markets the game as the first Super Mario title that can be played with one hand.
There are three mysterious figures in Shiverburn Galaxy(pictured) that the player can see upon entering first-person view. In the game's files, they are separate from the galaxy's background textures, and the filename of the graphics that depict them is "HellValleySkyTree". "BeyondHellValley" is the galaxy's internal name, "Sky" probably refers to this part of the background and "Tree" refers to the figures.
