Robert Topala is the creator of the side-scrolling, platforming Geometry Dash game series. The game was first launched on iOS and Android on August 13, 2013, then on Windows and macOS on December 22, 2014. In Geometry Dash, users steer a symbol through musical levels and steer clear of spikes and other hazards.

The creator of Geometry Dash created 26 lengthy levels, 22 of which are auto-scrolling and 4 of which are "platformer" levels. In addition, there is a quick level named "The Challenge" that has nothing to do with the other 26 levels. Players may make their own unique levels using the system for creating levels, share them online, and play levels made by other players. One may get in-game cash, including stars, moons, coins, mana orbs, or diamonds, from a variety of sources, like official and user-made levels and chests.
