First, thank you very much for you answer and your time.
I had done yesterday some research in fractal terrains (Diamond-Square algorithm, mainly), but I got overwhelmed with the implementation…
The sharp cliffs are ok, I’m doing it for the nostalgia after all ^^
I think I’ll try your pseudocode 
Regarding the camera, I think I have found a less conflicting way to accomplish what I wanted to do. It’s working almost perfectly now 
Now I’m working in a recursion function to draw paths for the characters, I hope it turns out ok 
I’ll try to give something to the community too, if anyone needs (Yeah, sure) a translation from/to english-spanish-german-portuguese-italian-french, PM me
