When a game is exported, you get a single “game.exe” and a “game.pck” file.
How can one manage to export a “Bonus Level” separately and deliver it to the game later without exporting the new combined game/bonus together.
Can the bonus level be a separate “bonus.pck” file and somehow called from the game without having to restart Godot ?
Or put it in another way: Can there be multiple .pck files in one Godot project ?
