Hello and welcome!
While the jam is primarily about creating and sharing Visual Novels, we don't mind stretching the definition a bit to allow for other kinds of videogames or story presentations. However, please do keep in mind that the jam is made by and for furries that enjoy engaging with stories or narrative-heavy games. (In fact, a lot of people in the FVN space aren't that enthused when VNs feature gameplay elements at all.)
So, in order to make sure this jam is the right fit both for you as a creator and for others as your potential audience, your entry should be a "furry narrative" in some fashion or other. If you think in good faith that your submission can fit under that definition, then it should be fine! If not, then probably this isn't the right jam for your particular idea.
