Thanks for taking time to write this comment !
The messaging application as a game element was the first idea I had for this project, and I developed upon it. I wanted a game where people could mix elements of their own life with the story, and see their old messages in a new light.
However I understood it could thrown off the experience, I'll try to integrate this a better way if I've similar ideas for next TTRPG !
Thanks again for your message! ♪(^∇^*)
