The objective of Covid Crush is to navigate a character through a maze-like environment in a timely manner while avoiding obstacles that move towards them. The character can move left or right, and there's a speed boost that can be triggered to accelerate the pace.
The core mechanic revolves around timing and reflexes as the player must adjust the speed to avoid colliding with approaching threats. The game world contains various types of objects that move at different velocities, requiring the player to adjust their approach accordingly.
The game takes place entirely in a browser, eliminating the need for a download or registration. The player's goal is to survive as long as possible without succumbing to the moving obstacles, increasing in speed and complexity as the game progresses.
