It is not possible to modify the e-mail address associated with the game, as your progress is directly linked to the game.
Because of this, we recommend that you check that your email address is spelled correctly when you register your account, as the game will take any email address you enter as valid.
Please note that if you wish to play the game using a different email address, you will need to create a new account from scratch, as it is not possible to transfer information between accounts.
