Geometry Dash Private Server where we have our own levels, our own in-game moderators, working top 100 and so on.
This GDPS runs on the most recent 2.2 leak, it happened in december 2019 when Robtop leaked new contents of the 2.2 Update on GD LIte.
The answer is related to the question above, the leak happened only on the playstore which means this GDPS is only playable on Android and on other platforms where Android can be emulated such as PC using Bluestacks 5 Emulator.
The biggest one is the Platformer mode, as you can see on the sneak peek by robtop himself (https://youtu.be/g4r6BTdU2M0), allows you to create 2D platformer-gameplay. This GDPS has also a lot of new 2.2 Editor features like particle editor, swing copter game-mode, new triggers like song trigger, timewarp trigger etc.
You can download the latest version of the GDPS in the #🔴-downloads channel, you can look up the changelog in #changelog and you can get roles in #self-roles to be aware about the next updates and announcements.
