What This Mod Does

This mod adds a small chance for any door to become a strange door. If you grab the wrong one, your world will distort, wave, and flip completely upside down before slowly returning to normal. It is basically a minimal and cursed version of the Upside Down.

The effect includes:

  • Screen wave buildup
  • Full world inversion
  • Red hue overlay
  • Drifting ash particles
  • Music

This mod is client sided. Only the person who triggers the strange door will see the effect. Other players do not need the mod. When you are flipped, other players still see you standing normally which makes it even funnier.

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.

Dependencies

Install these first, or the mod will not work:
