The main and operating character was supposed to be a walking tree, but I became emotionally attached to a little girl who lived in a house along the way.
The way the girl's story is shown is wonderful, and conversely, the contrast of the walking tree's story not being told at all is interesting.
It made me desperately call out to the girl as I was playing the game, "Run!" I called out to the girl to run away.
It was so impressive that I kept thinking about this game even after I finished playing it.
