Hello and good time of day.
Great game so far.
For "Lair development", dragon evolution, and other gameplay things you can check my game "Time for Dragons". Sorry, game itself only avaiable in russian language, but you can look to scripts - they was not protected in any way and you can take solutions and code fragments to enchance gameplay of Ravager.
