The Game Cleaner feature deletes the resources you're not using in your game. Specifically, resources that used to be a part of your game (you deleted them), but for whatever reason, still exist in your game's folder.
To use this option, it's located in the menu via Debug > Game > Cleanup Unused Files...
We recommend backing up your game before using this feature.
- This feature DOES NOT AFFECT THE FINAL SIZE OF YOUR EXPORTED GAMES.
- This feature only affects the on-disk size of the game and the size it takes up if it's shared on StencylForge.
- This feature used to be called "Optimize Game Size" and may still be referred to as that by some. We changed it because it misled people into thinking it would cut down the exported game's final size.
