[0.12.21] [Rseding91] Some strings can't be translated

[Juanjo]

I couldn't translate some strings:

• "Loading sprites ..." and other strings when starting Factorio.
• "Score" and "Rockets sent" appearing on the upper left corner of the screen.
• Name of keys: "SHIFT", "CONTROL", "space"...
• The "OK" button of the confirmation window for "The game is not saved, are you sure you want to quit?"

Thanks!

Item #1 and #2 and #4 should be simple to change to use localization. #3 I'm not sure if it warrants the time it would take.

Thanks!
I recently saw you added those strings to localization. Thank you!
For the "rockets sent" string, I don't know whether it is used elsewhere, but in the upper left corner I would add a colon if possible. (Rockets sent: __number_of_rockets__)
I understand that creating a table for translating the name of the keys, making it aware of the OSs and link it to Crowdin needs a lot of effort. Anyway, the game would look much better in terms of localization.
