I loved it! It's a fast and cute game with beautiful CGI, well-made sprites, a good variety of expressions, and an interesting story. I really love fantasy and mythological themes from Western culture (in fact, that's what first caught my attention. Something like "Oops, a kitsune").
Kai is a sweetheart, and I really don't have the courage to try to make the ending sad; it would break his heart and mine. I love him too much to do that. Especially after the adorable first ending.
I highly recommend it and will definitely continue following his games and work.
