Geometry Dash is a popular rhythm-based platformer. Released in 2013 for mobile devices and later for PC, the game has gained a strong fanbase due to its challenging gameplay, engaging soundtrack, and extensive level creation and sharing system.

Gameplay
Players control a geometric icon that automatically moves forward through levels filled with various obstacles, requiring precise timing to jump, fly, and maneuver. The goal is to reach the end of each level without crashing into obstacles. Players can tap or click to control jumps and other actions based on the game mode, and with each level’s rhythm synced to a unique soundtrack, the game integrates music cues with the obstacles and platforms.

Game Modes and Difficulty
geometry dash offers multiple official levels with increasing difficulty, categorized from "Easy" to "Demon" (the hardest). Players can also practice each level in Practice Mode, allowing for checkpoint saves to build skills without restarting entirely. Each level introduces new mechanics and gameplay styles, like flying a rocket ship or bouncing in gravity-altering portals, which make the game progressively harder and add variety.

Level Editor and Community Content
One of Geometry Dash’s defining features is its Level Editor, which allows players to create and share custom levels. This has led to a thriving community where players design intricate, themed levels and share them online. With thousands of custom levels available, players have an endless source of new challenges, many of which are highly creative and rival the official levels in design.

Expansions and Updates
The game has had several major updates, each adding new mechanics, level elements, and customization options. Geometry Dash currently has multiple versions, including:

Geometry Dash Lite (free with limited levels),
Geometry Dash Meltdown, World, and SubZero (spinoff versions with exclusive levels).
Popularity and Community
With a dedicated fanbase, Geometry Dash has developed a rich online culture. Content creators regularly post gameplay videos, level-building tutorials, and community highlights, and there are numerous forums and social media groups where players share tips, discuss strategies, and organize challenges.

Summary
