Feels polished. I didn't really get the story, besides the fact that she is worried that she is the murderer.
I wouldn't look the players camera and movement so often. For example when playing the tapes it's not needed. Or when you enter the bathroom on the fifth day. Also there should be a voice line on day three when you get the task to first talk to echos. Something like 'I should speak with the echos', because otherwise it feels kinda random. Also sorry for the late review, couldn't earlier due to my computer not cooperating. Last note, some days randomly end, like day one you go to bed, but on day 3 it suddenly ends after the cassette.
Has potential.
