I made a mistake my name…（ ; ; ）
Your name is determined by Game Center account, if you can change your username there. That should also reflect in WonderWorlds.
If you mean naming your level, it’s super easy to do. In the ‘Me’ tab, find your level. Tap on the name label, and you’ll see options to unshare. Unshare it and you’ll be able to Share it again and change the name
I’m sorry to late.Thank you yery muchˊᵕˋ
