tbh it does take some time to self-host miku.gg, I recommend creating visual novels on their site instead, its alot easier!
For more characters, I’m actually in trouble because the current version is outdated and I can’t update the framework without blowing everything up…
I’m more focused on my own little chat framework for the moment, you can take a loook at my other project: https://lyonade.itch.io/midnight-mirth-at-the-tavern
