While not 1.1, Geometry Dash World on the App Store is free and features remakes of very old levels. It scratches a similar itch without the need for hacks.

Since its release in 2013, Geometry Dash has established itself as a titan in the rhythm-based platformer genre. However, for a dedicated segment of the player base, the official experience offered by RobTop Games is only the starting point. Enter the GDPS (Geometry Dash Private Server): an unofficial, community-run alternative to the main game. The phenomenon of the "GDPS download"—the process of acquiring and installing these modified clients—represents a fascinating intersection of software modification, community governance, and the desire for creative freedom. By examining the technical process of accessing these servers and the motivations behind them, one gains insight into how modern gaming communities extend the lifespan of their favorite titles.

Now you can save levels, comment, and upload your creations.

Be careful when downloading modified game clients. Always scan for viruses and ensure you are downloading from a reputable community source (like the GDPS owners' Discord) to avoid malware.
