The only thing I remember is that I am "human" being. In my sight, there is a vast world of nothingness... and a huge world tree shining in rainbow. Why has the world become like this? What does that world tree exist for? Why I can recognize "that" is a world tree by just one look? I must understand about this world and about myself. I had nowhere to go anyway, so I started walking to the tree. #System Requirements Works with iPhone8 or more.
