Geometry Dash shares similar elements with The Impossible Game in terms of basic level components and cube gameplay mechanics.All main levels begin with a regular cube sequence.Entering into and exiting out of any of the three primary menus will always result in a cube being the next icon to pass by.The icons exclusive to the Steam version of the game can appear for other versions.The unique mini designs for the cube and ball can appear at the normal size for each.Spiders will only ever be the design that is currently selected in the Icon Kit.They can be selected, which will destroy them. On the main menu, normal or mini icons of any customised combination will travel past randomly.The Geometry Dash Menu Theme was composed by the developer, Robert Topala, accessible from his Newgrounds profile RobTop.
