Zootopia is an interesting place to use as the basis for an interactive. They have a very wide range of characters so it makes for some wild possibilities. This interactive is still early in development but you have a good setup going allowing writers to introduce their own original characters into the Zootopia world.

I am also glad there is a segment for for the series leads like Judy Hopp and Nick Wilde. Hopefully we will get to see more story arc getting added to this. I recommended having at least one good storyline going to set the tone and encourage other authors to read and add to it. Good luck with your writing.
