Geometry Dash Extension - At The Speed Of Light: Hard-Demon Rhythm Challenge

Geometry Dash Extension - At The Speed Of Light delivers an intense hard-demon difficulty experience synchronized to dimrain47's iconic "At The Speed Of Light" track, featuring precise spacebar or mouse click controls for ascending movements throughout challenging platforming sections.

Technical Portal Mechanics and Considerations

This level includes specific portal interactions that advanced players should understand:

Potential to pass under the initial purple speed portal while maintaining 1.5x velocity
Possible navigation over the first down gravity portal while retaining normal gravity orientation
Restricted input requirements when hitting down portals - only one spacebar or mouse press allowed before reaching subsequent upside portals

Development Background and Verification

The creator initially developed this as a demon-level project requiring approximately 80,000 attempts to complete before temporarily shifting focus to Blast Processing. Persistent development efforts eventually resulted in verification and publication of this challenging extension.
