Actually, this is good, but I just don't really think this should be called a game.
I'll prefer that we can search more details like things on the table, in the closet.
Though we can walk in rooms, only moving right and F to go in a room and go to bed doesn't seem that great for gameplay.
I usually play games before I read the introduction which is author's comment.
It's easy to tell that this game wants to say something that things can come back like we can't walk back in the corridor, but it's not that clear what kind of thing that author really wants to talk about.
I'll play it just once, or maybe more. But it's not that kind I'll like to share, recommended to others.
BTW I like the BGM and graphics.
