This shows how (almost) any engine can be used for quality production, as long as the artist's and developers have a vision and stay dedicated to it. Who would have guessed this is Unity engine? All the underdeveloped and cheap games that are made with it don't do the engine justice! Great work!
thank you very much guys! @sinking: well as long as you can chage whatever you need sure lots of engines have the potential. Ori has tons of custom tech wich made it possible, out of the box unity would definitely not cut it.
