Thanks for your explanation. I guess that given what you describe there the rain may indeed have that effect on the player. In this case it still sets a darker setting and ironically a ray of hope.
And yeah, translating can be a good idea. If you look at my RPG games you'll see you can play them in both the English and the Dutch language and even though I used a special tool to do this rather quickly, it was still a lot of work. But I think was rewarding somehow.
