I'm not sure exactly what's going on but when I go into settings, I can't assess the list of settings to the right just the command list? I kinda feel stupid here. Also, the controller works on my dualsense, but I don't have any correct button prompts. I'm thinking about contacting support to see if this is an issue they will address because if I just see Keyboard prompts I'll be confused.

I was really excited to play this, especially with a PS controller like when I was a kid, but maybe I'm stuck with keyboard?

I’m gonna go out on a limb here and ask whether once you highlighted the particular options category did you hit a button to confirm your choice/enter the submenu? Confirm is x and cancel is triangle. The game only displays numbers and not buttons at this time.

I wasn’t able to access the sub menu. I tried everything I could only scroll the four or five options on the left menu in settings. I couldn’t get to the right side displayed settings.

Does it work if you use keyboard? Try pressing the arrows keys and "C" to confirm.
