Thanks for playing and for the feedback!
I already made the fires brighter (for a WIP update): 
I will also address the clouds issue with either making them invisible on mouse hover, or a setting to disable them completely.
The fires give faith when extinguished, so you could let them spread in order to get more faith btw
you can place many building on the charred lands, and I might give bonus to farms (inspired by real life). Also I decreased the prices of the meadows and forests significantly.
But I'll think about it. I think the extra faith is mainly useful in the early game.
BTW, in the future, faith will not be used to buy build cards from the shop, but for something else :)
