This is a PERMANENT ACTION. Twisted Towers Support cannot recover a deleted account. You will lose any purchases you made in addition to the progress achieved in the game. If you choose to start over with a new account, it will be from scratch. We cannot transfer a purchase from one account to another.
If you're certain that you want to delete your account, start by pressing your avatar in the upper left corner of the screen. Go to, "Accounts," and then, "Manage." Press, "Delete." You'll have to type the word in the text box to activate the button before you proceed.
