Very interesting idea. I like the messaging system and what you are doing with it.
The notes when they pop up don’t let me go back and check, which I don’t know is intentional or not. Also I didn’t realise what it was for the first time so I clicked something that wasn’t completely correct. or was it??
When the Second chat opens I could not continue. In that chat I can type anything but would not send. So I got stuck there.
Also are you coding in C# or Godot script? If it is Godot script you should be able to export as a web version. Also, add a way to exit the game with a button press.
