Ahh, it's great to hear your all your thoughts, all good things to keep in mind for possible future games (who knows?).
I agree, we could've definitely used more of the game-exclusive possibilities, like the "start writing" and the sound effects. (Difficulty is no excuse, once you found out how to program it once, you can just reuse that, haha.) But there are probably even more things one could do in that direction!
Personally I kinda dislike miscommunication to add drama, but then again it often happens in chats that you write one thing and the other person interprets it very differently. There's surely a way to add some of this without making it annoyingly overdramatic. (You know that moment when you wanna shake the characters bc they haven't spoken once in 3 years to solve this one tiny little problem? xD)
Anyway, ty for the long comments and glad you liked the background too! Isa worked hard on (most of) them :)
