Geometry Dash Meltdown

Geometry Dash Meltdown is an expansion app of Geometry Dash developed and published by RobTop Games and released on December 19, 2015 for iOS and Android for free. It features three exclusive levels, achievements, icons and secret coins, with the ability to transfer certain unlockable data over to the full version of Geometry Dash through user accounts.

Trivia

 * Although Robert Topala stated that there will be "five brand new and free levels" in Geometry Dash Meltdown, only three levels were initially released. The Coming Soon screen tooltip states that "There will be more levels, but are you prepared?".
 * Stars do not serve any purpose with no related achievements.
 * Geometry Dash Meltdown includes achievements for collecting all three secret coins in levels, a feature exclusive to the demon difficulty levels in the full version.
 * The Icon Kit resembles that of the full version despite being unable to unlock icons which have not been introduced to the Geometry Dash Meltdown.
 * The soundtracks, The Seven Seas, Viking Arena and Airborne Robots are not available on Newgrounds and were instead released as part of F-777's albums, Pirate Dance Machine, Viking Dance Machine, and Ludicrous Speed.
 * The music offset upon getting the game is automatically set to 2,147,483,647 (231 – 1) milliseconds. This is shown when the player pauses the game and continues, causing the music to restart even when in the middle of the level.
 * RobTop replied to a comment on TouchArcade, asking if the Meltdown levels will be added to the official game when loading a meltdown save, to which he replied, "Maybe in the future."

v1.0 data transfer trivia

 * The ship unlocked by completing Electroman Adventures in normal mode is shown on the game's cover image, but is not able to be unlocked in-game.
 * By destroying icons on the main menu, colours and cubes can be unlocked with the exception of the 'Wickedsick' ball.
 * If the cube is selected that requests to rate the game, it will provide a redirect to rate the full version. The cube that is locked will show but it will not be available to use.
 * It is possible to access the Vault by loading a save with it unlocked, although entering codes will not work and the background music does not play.
