This game stood out to me greatly when I first saw this way back when. I commend you for trying your best in creating something so personal! I've been there before and it can totally be very draining to make something based off that experience. I also applaud you for being very open about how it affects you.
In terms of the theme, I can see how story wise it really fits in, both in terms of what's in the game and what isn't. The dialogue choices were hard to pick through, in a good way, because damn does it seem like there really isn't anything to say in such a hopeless feeling situation, which I think was what you were going for!
If you ever do continue this I hope you can find a good balance of using your personal experience as part of a story while combining it with other aspects of story telling that you personally like. Great prototype! Genuinely excited to potentially see more of this idea/similar ones.
