Astonishing what you have created in just a week. The art is beyond amazing! Truly :) The story itself is really interesting and is paced extremely well. It you were to update this I'd wanna see some hints of the monster in reflections of glass or mirrors, like you see it for a glimpse before it disappears (just a suggestion not a criticism).
This game is amazing and really well put together. The polish is amazing! My only small gripe would be the character walks a little slow for me. I know you want to build up slowly in a game like this, and perhaps this opinion is mine alone, but since part of the game is walking around and finding the next story beat, I would have liked the character to move faster.
But yea, truly incredible! Great job :)
