Okay, we had "blook" the other day, now we've got "wovel".
I had to google it and found out the main hit is for a mutant snow shovel. Pronounced differently, I assume.
Anyway, the term seems to crop up around
UNDERLAND PRESS, a creation of ex-DarkHorse editor Victoria Blake. They publish traditional books by their authors...and wovels.
This seems to be a little different from the "blook" or "blit" like I'm doing. The idea seems to be more like the old interactive story. It's a running serial that stops now and then for the reader to make choices or alter the direction of the story.
