Ratings and reviews

At first, I thought this was going to be another typical AI app, but I have been hooked since day 1. It's fun and exciting to see everyone's creations. New features are being added. I do wish we could delete pictures that don't fit our summon and be able to choose 4 images we want to use for our collections instead of just 1. Hopefully it'll be added in the future.

I like the app, but 120 characters aren't enough to fully portray/ describe the character I'm trying to create. Honestly, if you could bump it up a lot, that would be nice. I'm talking to at least 500 characters. Edit: As of 10/30/23, i saw the chara ter limit was bumped up to 200, which is nice. It's not as high as I would like, but it's a good start.

Trying to summarize what's happened into lines fitting under 500 characters can be really hard. Wouldn't mind if y'all added an AI assistant feature there that can help you analyze the game so far and help summarize what the AI has learned about the world so far, in a format that works to be read by the LLM. Like, some impressions should last, but can be summarized over time "he put a sword to her throat" could be summarized as "threatened me when we met" to "first impression threatening".
