Take on one of the most difficult challenges in the Geometry Dash universe with Sonic Wave Silent Circles Challenge. This extreme demon level, rated 10 stars for its impossible difficulty, has been carefully balanced. Thanks to @Aspect_GD for fixing bugs and creating the thumbnail. An update on December 11, 2022, saw the beginning nerfed and buffed to make it possible, with additional difficulty added later to ensure the entire level is a balanced test of skill.
Due to the complexity of this extreme geometry dash level, a Lag Warning is issued. It is highly recommended to use Turbowarp or Turbo Mode for the best experience. Access the project directly via the provided Turbowarp link. For detailed editing tips, refer to the Scratch guide. The game also functions as a powerful editor. You can Add Music by modifying the backdrop and Save Levels by remixing the Scratch project. Control is split between Player and Editor modes, toggled with Z/M. As a player, click to jump, fly, and interact. Use I/O for the 'no-clip' option, a valuable tool for geometry dash practice mode online, and vote 0-9 on the endscreen. In practice mode, press Z to set checkpoints.
The Editor Controls are extensive: use number keys to navigate menus, place blocks, rotate with R, and access trigger (F) and debug (O/P) menus. The Version History highlights the powerful features at your disposal. Version 2.0 includes major additions like save codes, numerous triggers (move, alpha, instant count), keys, coins, colored blocks, glow, teleport portals, 3D objects, thorns, the swing copter, more monsters, and fade effects. This allows for the creation of intricate geometry dash custom levels online. The foundational Version 1.0 includes all core game modes and building blocks, making this a complete package for both playing the hardest geometry dash level and creating your own.
