Is there any geometry dash levels that contain explicit content

Yes, there are some user-created levels in Geometry Dash that may contain explicit content, whether through inappropriate imagery, themes, or music. The game's community allows for a vast range of creativity, which sometimes leads to inappropriate content slipping through. However, the official levels created by the game's developers are generally appropriate for all audiences. It's always a good idea to use discretion when exploring user-generated content, and many players opt to avoid levels that are tagged as having inappropriate themes or content.
