What it does

MoonWalk RD is a small physics tweak for the earliest known version of the game, rd-132211, a RubyDung-era build. It changes how strongly the player is pulled toward the ground, so falls are slower and the character stays in the air for longer after a jump. Pressing G toggles the low gravity mode on and off, which makes the setting simple to test while exploring a RubyDung map.

The mod is distributed as a Java Agent, so it is not a Fabric, Forge or NeoForge mod and needs no loader API. Installation is done by editing the rd-132211 instance and selecting the MoonWalk RD.zip file, then launching the game. Only the client runs it, and the mod is released under the MIT License but is not open source. Snapshot builds are published, and the files target the single game version rd-132211.

Key features

  1. Low gravity toggle

    A single key switches the player between normal gravity and a reduced gravity setting while the game is running.

  2. Floaty movement

    With low gravity active, the character falls more slowly and remains airborne longer after each jump.

  3. Instance-based install

    The agent is added by pointing the rd-132211 instance at the MoonWalk RD.zip file before the game is launched.

  4. RubyDung map exploration

    The low gravity setting can be tried on a simple RubyDung map, where the altered jumps and falls are clear to observe.

No per-version build data
Modrinth lists game versions for this project (rd-132211), but the source data has no build per game version and loader, so the compatibility grid is not shown.

Questions

Which game version does MoonWalk RD work with?

The mod targets only rd-132211. Its files are published for that single game version and for no other release.

Does MoonWalk RD need to be installed on a server?

No. Only the player's game needs it, and servers run without it.

How is MoonWalk RD loaded into the game?

It is a Java Agent rather than a loader mod. The MoonWalk RD.zip file is selected in the rd-132211 instance's Edit screen, and the game is then launched.
