This has previously been answered elsewhere in this thread, there are jam revolves around two things Light Novels and "transformative experiences". This Jam comes from the community around Alex Zandra Van Chestein and her narrative light novel universes both nicknamed the Zandraverse, this is a very lgbt+ and light novel loving community
What does this mean? : Firstly the entry needs to pay homage to Light Novels and essentially their flavor, the silly titles that act as a synopsis, the types of narratives that are arch-typical of the style etc. E.g. "My Friend Took Me To A Feline Therapy Place For My Anxiety And I’m Starting To Wonder Where The Cats Are?"
If your entry is literary this is pretty easy it is really just a matter of length, if it is using a game structure it could be a light novel flavored visual novel, a light novel themed choose your adventure story game or just a game that has a light novel style title and story arc. If it is a comic, it likely will be a comic playing at being a light novel possibly similar to how a manga one-shot can be made of an existing light novel. If art there are two ways to go about doing this, designing a fake light novel cover with fake title and cover art, or perhaps an artbook/art collection that would be the illustrations that would often accompany a light novel.
The other jam theme is "transformative experiences", this can be physical, emotional, spiritual or a change in mindset: possible examples including transgender themes, discovering sexuality, perhaps being changed into a monster, a princess or a fridge or a character going a set of circumstances that transforms how they think or feel about something major. It could even include a mixture of these.
The only real restrictions around this Jam is keeping to the spirit of those two requirements, having fun, giving things a go and being kind to others.
