Great use of the theme! The dialogue had a very personal feel to it which kept me engaged. It was a bit inorganic in places and the player character could come off as a bit preachy at times. It didn't feel like the dialogue choices had much of an impact on the overall direction of the conversation. I would also recommend doing a spelling/grammar pass again as there were a lot of errors.
The video in the background looks nice but it loops a bit too frequently to the point of being distracting. My main suggestion is adding a hovering effect to text you can interact with even if it's just highlighting the text. Also an "Exit" option at the end of the game or having the app close after a few seconds.
Overall one of the more thoughtful approaches to the theme. Great work!
