Here is the catch: If you edit your save file or use mods while connected to the internet, your account will likely get "flagged" (indicated by two tiny leaves behind your settings icon).
If you want to speed up your progression safely, let me know:
BTD6 receives frequent updates. A save file from an older version of the game may not be compatible with a newer one. Loading a mismatched save can have "undesired effects such as removing all trophy store items". Ensure your game is updated before you attempt to edit, or use a save editor that is compatible with the latest patch.
