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?
Those are my favorite ones.
Raging Loop
Yu-No
AI: The Somnium Files
Zero Escape trilogy
Danganronpa trilogy
Most don’t really have multiple endings, but some of those titles have a story branching mechanic that might be of you interest.
Edit: Here’s a visual novel database if you are interested. This is the same site with the multiple endings tag applied.
