Added support for game version 1.11.240.0.

feature

This mod removes the 500 mph speed limit in game memory, causing uncomfortable jerking/stuttering when sprinting on uneven ground. This is because when the speed is greater than or equal to 500, the code used to align the camera when the bird is flying starts executing. In this case, the condition is not used on the fly because there is another condition above.

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
