I'm out of ideas

What I mean is, what is the goal of the interaction? Most of my talkies are designed around some kind of implicit or explicit objective, usually involving a choice, argument, or discussion. If you know what goals you like to create for your talkies, it might make coming up with ideas easier. If your interaction goals are too vague, it may become hard to narrow down your focus for ideas.

How is Sister Bella intended to be interacted with?

I personally don't find random ideas from people very helpful, but I have gotten plenty of inspiration from interacting with talkies, both my own and other users. You could also try branching off one of you existing talkies. Which one of your talkies would you consider your best work?

Are you looking for general inspiration or a process on how to form ideas?

If you need ideas start by deciding what kind of experience you want to create for your audience.
