besides the evident and lazy use of textures in the mountain, most of it has been shaded with brushes and gradients.

I have already answer to that, The big party of that is pixel.
And none brush have been used (the mountain is a some of tiles I used, and the only moment I didn't use the pixel was for some shadow (for some building) but it's in majority pixel art.
