First of all, Everything that is designed by a human is copyright protected. You’re not allowed to copy a whole UI verbatim. It’s their intellectual property. However: The individual buttons, or offering options ‘New game’, ‘Load’, ‘Exit’ might not pass a threshold of originality. You need a certain level of creativity to pass for copyright protection. And you can do a similar design, just not rip it off. For example a medieval style is not something that is protected. You can do a medieval style if you come up with the design yourself. You cannot take their code or do screenshots and use them. So if I read your question meaning just do similar layout choices, then No. That’s not their intellectual property. Unless it’s super unique to that specific game. Just the exact layout is.
