Great story and presentation. While the ending is not completely conclusive, the plot is covering just enough to deliver the theme. I can't really pinpoint the issue, but I do think there's something missing before curtain call, making it just a little bit unsatisfying.
The visuals and audio are amazing, I just wish the sister could have more screen time. Also, I totally love the JVN vibe of the UI. Only problem for me is the text on the middle of the screen could be difficult to read sometimes. Perhaps darkening the screen would increase the contrast and fix the issue.
Awesome work ^^
