About the game — TGN editorial note
Geometry Dash is a rhythm-driven action game where players steer a simple icon through obstacle-filled stages timed to music. Most of its official levels scroll automatically, while a few use free platforming, and a built-in editor lets the community build, share and play custom stages. Swedish creator Robert Topala made it under his company RobTop Games using Cocos2d-x; it launched on mobile in 2013 and reached Steam in December 2014.
