PLEASE HELP . – Block Bros: Platformer Builder Review

I have played this game since 2015, and I want to log into an account again, I know the email and the username of that account but I am unable to log in as it asks for an ID. Im pretty sure you didn’t need to type an ID to log into your ID before, so I don’t know what it is because I can’t log in :/ Please help!!
