I use a controller so continue is already highlighted. However, I have to press a key twice on the "press any key to continue" screen. The first press changes the prompt from "key" to "button" and then a second press proceeds to the menu.
I really wish it'd save your settings to force controller interface between sessions. I submitted a report around launch and it seems they still haven't implemented it. It's not a big deal, just mildly annoying.
There is a setting for "controller only" that I don't have on because there's a couple spots where the controller interface doesn't allow me to click on something embedded in walls; that might actually fix this little annoyance. But then you wouldn't be able to use the mouse or keyboard seamlessly without changing it back. Personally, the clicking on the walls thing is more of a problem, since it actually affects the flow of the game. I would like the stick controls to be "unlocked" and let me move that thing the same as the mouse. I would have thought it would be fixed by the time the PS5 version was launched, because some of those players are likely to experience these issues.
