Nice! I have the impression that it would be bit too dark for me to play (especially the red path, yikes), but I really like the prompts. They are quite vivid.
Have you playtested this? I wonder how well the Dialect cards match up with the aspects, and how easy it would be to come up with the shared moments.
Anyway, I happened to use the same tweet as inspiration (it's gold!) but I took a very different approach: I made a new game instead of literally using Dialect, and made it much lighter. In my game, the couple has already broken up and they are remembering good moments. There is even a small chance they will go back together!
