A community for fans, devs, and general aficionados of the adventure game genre. This includes IF/parser games, point-and-click games, puzzle games, walking simulators, and whatever else you want to call these. To us, they're simply adventure games.
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.
I'm totally blanking on if they have multiple endings but I love Digital: A Love Story and If Found. I also liked We Know The Devil and A Summer's End - Hong Kong 1986, which do have multiple endings, but are a little more adult. All are fairly short. Ladykiller in a Bind is more comedic since you're looking for something along those lines and each playthrough is fairly short although that has more player input than the other games I mentioned.
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.
