I’ve just finished the RC, and I was watching the credits to ensure that my translations were OK there (I had to make some strings shorter, but that was expected).
And I noticed that the credits screen never ends. When the credits finish, the music continues with a black background, and it does not end by itself (which is what I expected). It does not finish either when you press one of the regular keys (e.g. F or D), which is what I though next. So the only way to get back to the main menu is to use the game menu (Esc).
Is this on purpose? I do not have a strong opinion about it or anything, it just seemed a bit odd.
