I thought that can I make good things working for only free assets on Unity Store. I have just started yesterday this game, Survival in Space, but I learned Lightning and Post-Processing on Unity, a little bit. This is the first screenshot, in-game editor. If I succeed some good thing with free assets, I will buy some good assets for game development with Unity 5.
