Geometry Dash is a popular series of rhythm-based platformer games developed by Robert Topala and published by his company, RobTop Games. The game series is known for its challenging gameplay, vibrant geometric graphics, and catchy electronic music.

The gameplay of Geometry Dash (Geometry Dash Lite) involves guiding a square, often referred to as the "cube," through a series of obstacles, spikes, and traps in various levels. Players must jump, fly, flip gravity, and dodge obstacles in sync with the music to progress through each level. The game tests players' reflexes, timing, and hand-eye coordination as they navigate through increasingly difficult levels.

One of the key features of Geometry Dash is its level editor, which allows players to create their own custom levels and share them with others. This feature has led to a vibrant community of players creating and sharing levels, contributing to the game's longevity and popularity.

Over the years, the Geometry Dash series has expanded to include several versions and spin-offs, each introducing new levels, mechanics, and challenges. The series has garnered a dedicated fan base and has become a staple in the rhythm-based platformer genre.
