Found an outcome case that I had overlooked, so I updated the scenario file.
For Windows, copy the file to either .mods/scenarios in the game folder (overwrite the existing file), or to c:\Users\YOUR_USER\AppData\Roaming\Godot\app_userdata\Battlefuck Pit\.mods\scenarios\
For Android, download the file to your device (preferably to the Downloads folder), then launch the game, open up the File manager under Options and create a scenarios folder under .mods/. Enter the new .mods/scenario folder. Select Import file, find the file you've just downloaded and select it. It should now show up in your game user folder.
In both cases, you must restart the game. The game will use the new scenario file.
