Hey man, I've just released the game and I'm happy there's already people playing it! Your idea is very great, I will note it down to add it in the next update! Thanks!
by the way, would you like to collaborate with me? We could make a Lumber Company Tycoon 3D game. I recently programmed an asset for Unity that would allow us to make a random world and then add a shop, different worlds with different types of trees and more... (procedural). If you use Unity of course (:
