moved to free collaboration.
can you be more detailed about what you need? like, do you need to create new characters or fanart of ddlc characters? by "how they interact" you mean you need help with writing?
and can you say what's your game about? do you have a plot?

this is just my advice, but if you don't explain your idea properly, it's very hard to find collaborators because they have no idea what's the thing about. more you explain and higher is the chance to find collaborators

I'm no longer working on anything. Collab is okay, But there is a high chance I may say.. No.
