A mod that replaces jumping with flipping gravity.

About this mod Author’s original text

Glissando

or: "Even a Wyrm will turn"

A Hollow Knight: Silksong mod that completely replaces jumping with flipping gravity.

Inspired by the game "VVVVVV" by Terry Cavanagh. Sponsored and playtested by TherminatorX.

Double jumping is also changed in this mod. And to make traversal a little more reasonable, once float and double jump are both unlocked, you can always press down and jump in the air to float.

Included in the mod's options is the ability to force a hazard respawn, with either menu button or keybind, in case Hornet ever gets stuck somewhere or goes out of bounds.

Acts 1 and 2 have been playtested, but you may still encounter some problems. If you find a glitch, please open an issue on the Github repository.

Therm's challenge: how much of this mod can be beaten with the Mount Fay upgrade disabled?

Installation

Install via r2modman or Mod Manager. Glissando's dependencies should be installed automatically.

For manual installation, extract the.zip file and place the resulting folder in the BepInEx/plugins directory for your Silksong install. You'll also have to manually install:

  • FsmUtil
  • I18N
  • ModMenu and its dependencies

For Mod Developers

If you're developing a mod that changes Hornet's velocity at any point, the y velocities you set may not automatically flip when Glissando flips gravity. This is especially important for custom crests and tools, as any new FSM actions you add will not be affected by this mod.

If you want your mod to be fully compatible with Glissando, you can check the value of the static boolean property GlissandoPlugin.GravityIsFlipped and invert any relevant y velocities or movement when it's true.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file.

Install these first, or the mod will not work:
