The atmosphere and the sound design was really well executed.
The first thought I had when playing was "Oh wow, this looks beautiful" and, honestly, I wasn't expecting such a gorgeous game to get as scary as it did!
It might be a skill issue, but I got lost almost as soon as I wandered off. Not sure if this was intended, but if not, maybe some landmarks in the area would help guide players. I feel like something like a weird rock or having torches near the ring would help guide players from far away.
