Visual comfort: you can adjust the size of the on-screen controls, and activate or deactivate the enhanced brightness.
Touch controls: you can choose between a fixed or floating joystick (visible or invisible), as well as activating automatic movement and hiding the up/down buttons for swimming.
You can also choose a button style and adjust the camera speed.
In the Options > General menu, you can also choose to activate subtitles and adjust their display speed.
If you are sensitive to flashes of light, you can disable flashes in the Options > General menu.
