You can't directly remove a player from your Animal Crossing: New Horizons island. However, there are a few ways to manage player access:
1. Changing User Settings:
- Change the island's owner: You can transfer ownership of the island to another player. This will make the original owner a regular villager on the island.
- Change the user's permissions: You can adjust the permissions of each player on your island. This allows you to restrict what players can do, like building, placing items, or interacting with villagers.
2. Resetting the Island:
- Delete the save data: This will completely erase your island, including all progress and player data. This is a drastic measure and should be used as a last resort.
3. Managing Friends List:
- Remove the player from your friend list: This will prevent the player from visiting your island through the friend list. However, they may still be able to visit if they have your Dodo Code.
It's important to note that removing a player from your island will not delete their character or progress. They can still access their own save data and play on their own islands.
