The definition of the kind of entries that are accepted is not fully specified. The types of entries listed in the Entry Format suggests that literally any form of creative work is generally accepted as long as it relates to literature on some level and is not a full scale novel. However, the name of the jam and the random references to light novels suggests this is supposed to be about creating light novels.
This is very confusing as light novels are a very specific literature format, but half of the jam description acts like this is not about light novels while the other half does.
And so which actually is it? As this is the entire basis of the jam.
