You can also premultiply w with a, as every occurrence of `w` looks like `wa`. This should shave three more bytes: w=g-gexp(...),g-=wa,c+=wad9.+...,c.r

You can also premultiply w with a, as every occurrence of `w` looks like `w*a`. This should shave three more bytes: w=g-g*exp(...),g-=w*a,c+=w*a*d*9.+...,c.r+=w*a*a*2,... w=g-g*exp(...),g-=w*=a,c+=w*d*9.+...,c.r+=w*a*2,... (I've tested this with the Shadertoy version. YMMV.)

This is not equivalent; the `a` in `c.r+=w*a` is different, you need the original untouched w. The mountain looses its crack with your version. But! You can save 1 char by replacing w with a: g -= a*=w, c += a*d*9.+... a = min(...), c.r += w*a*a*.2, So thank you for the idea!
