It's not a bad start. Personally, though, there are a couple of things I'd like to see improved:
- The resolution doesn't take up the entire screen (I'm playing on Android) and so there's always a moving background which is very distracting.
- When messages arrive from characters, the chat scrolls to show them, but when messages from the MC are sent, the chat often doesn't scroll and you have to do it manually.
- The messages continue whether you are looking or not, which is very annoying since you are not notified of who is writing and there is not even time to see the posts with the photos, I think it would be better if messages only scrolled while you were in the chat and maybe a notification icon to let you know immediately which chat to open.
