It's still a prototype and may not have a game objective yet,
It was fun to see the exciting concept of a cute unicorn adventuring in a very large fantasy world!
It's a girl's dream come true!
Come to think of it, I happened to have played a unicorn 3D adventure, also based on unicorns, that was created to fulfill the wishes of other people's daughters.
So a unicorn adventure is a girl's dream itself!
