@denis_eps Yes you can use the options menu (in game). Apart from that we are currently working on an improved "so called" vs. Screen which will enhance the UX for the players (giving more info on what scenario is played and so on)
Did you enter wrong login details repeatedly? If yes, your account will be temporarily blocked as a security measure. However it will automatically unblock and you'll be able to login again. Otherwise please let us know if the problem persists.
