Very impressive work for one person. Everything felt bleak, but believable, which I think was the intent
I think this kind of story is really easy to symphatize with - the moments that grabbed me where actually not with the written text, but little things such as the floating objects and the calendars on the wall - this is where I felt the interactive element of the game shone through.
If I have to nitpick - stuff like invisible walls on the park pulled me out of the experience a little bit - but still, it was very well done!
