Seems pretty fun so far! My main problem right now is trying to continue the first story. It wouldn't be so bad If I could post what I've edited so far and then add to it after- That seems like an easy feature but I don't see a way to edit stories after submitting it. I keep trying to edit the story but an error (failed to Regenerate) happens or I leave and the continued story is gone. A simple fix is to make submitted stories editable. UPDATE: they added a draft feature which is a nice comp. :)

I love this app so much, but it's getting worse after the update, sometimes the next episode loading cannot loading finish, including sending text, since the update. seems like your tech don't really keep up with modern style. use everything classic version, don't add such settings, make everything simple like whatsapp, then the most problem might be solved. since it's your app, i think you know what I'm talking about. and the most problem and most complain from people, character lost memories.

The AI mechanics are amazing. Though sometimes, when you write a chapter in the story that doesn't load or loads very slowly when the dialogue doesn't show up and you have to delete the chapter of the story, then rewrite a new one, and the music function doesn't work. wash my treadle, create a character. I just go blank. It won't show a picture of a character or anything.I'll just go blank preventing me from making any new characters.
