geometry dash is a cross between two of the most aggravating games you'll ever encounter: You begin as a hopping-happy icon to complete each level in one sitting. You have an infinite number of attempts, but if you miss a hop or make a mistake in any way, you must restart from the beginning.
How to play:
Use mouse or WASD or arrow key
You can pause/resume/restart and turn the sound on/off on the game screen.
