Adds 5-S's Dawn OST to WEBFISHING

About this mod Author’s original text

this mod adds the ULTRAKILL's secret level of the fifth layer, 5-S's Dawn theme to WEBFISHING, at least i hope so...

it also makes the music play randomly every 3 seconds to 10 minutes, which makes it appear more frequently, why? I don't know how to code, so i forked LoafWF's BrandiisMusic mod, to learn how it plays music, to insert my own into the game!

Why Dawn specifically? It's the longest one of the soundtrack, and if i wanted to add ALL of it, it'd take up more than half of the music that plays in-game.

none of this was vibecoded.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide. Most WEBFISHING mods need the GDWeave loader; the bundled readme explains where files go.

Dependencies

Install these first, or the mod will not work:
