I find that odd. Come on, you must have a word for “Cancel”, half the buttons on Windows say “cancel”.
No menus in your country? Then how do you order at restaurants?
If 3/1 means 3.1 in your language, then just edit the phrase for . and type in /
Music and background should be easy, because you’re not supposed to translate the episode names (just leave them in English).
Skill names are tough, but definitely doable. If you don’t know, just leave them empty and some other player will do them. Or, you can just use “very easy”, “easy”, “medium”, etc.
