Hello, I was the one who asked you about custom levels. Listen, you don't have to add this, but please, can you at least give me an older version of the game that has this mode?
https://github.com/Poobslag/turbofat/releases/tag/v0.8700
Version 0.8700 has the level editor on the main menu.
If you end up using this version, make sure to back up your save data first to avoid game crashes or lost data. On Windows, this will be at `%APPDATA%\Godot\app_userdata\Turbo Fat`
