Geometry Dash is a rhythm-based game where players must navigate through a series of obstacles using a variety of different game modes. One of the hardest levels in the game is Wave 23. Wave 23 is a wave level that is known for its fast-paced gameplay and unforgiving difficulty. It is considered even harder than Cube 146, and it has only been beaten by a few players. The Cube 146 icon is a simple but effective design that perfectly captures the essence of Geometry Dash. It is a symbol of difficulty, skill, and determination.
