Yes this is outside the scope of “Adventure” and “Point-and-Click” games, not really sure if the Narrative genre would be something different from visual novel.
I played two games by NeiLei on itch.io that were a little over an hour long each. Funny and the art was nice. Most of the games were watching the dialog, there was very limited player input but it was there.
Any suggestions for similar games that are 99% story, with different endings?
The Coles are experimenting with making visual novels-- see Summer Daze: Tilly’s Tale. Mostly because it’s well suited to their artist’s art style and (in theory) quicker and simpler to produce. Long Live The Queen, Dream Daddy, and Loren Amazon Princess were inspirations.
Not sure how much crossover the VN community has with adventure games in general.
