What a great atmosphere! Point&click games are quite rare, but always welcomed =).
Okay so first, the graphics. They are GORGEOUS. The little cutscenes, the room that changes when you sleep... Everything is absolutely beautiful and sets the tone of the game. The ambiant music also goes perfectly in that way, and contributes beautifully to the general mood.
The puzzle were quite simple, and the game was quite short, but it's a 7-days game jam, so it was expected. Don't take it as a "it lacked content", but more like a "It was so good that I would have enjoyed more of it =p". I absolutely loved the touch of "going into the computer's settings to set the volume". I don't know why I loved this idea so much, but it made me think of NieR: Automata's beginning, when setuping the volume is part of the gameplay ^^.
So yeah, overall that's a great game, and I would love to play more of it if you plan to expand the story/universe after the jam =).
