Got DS? There's a small handful of decent VN's for DS. (I think. I'm classing a VN as being something with a lot of reading and the odd interactive segments.)
I'm not too up-to-date on VNs, but here's what I can think of.

9 Persons, 9 Hours, 9 Doors - DS VN by the guy who created Ever17 or something. Very neat story; no hershey kisses, but puzzles instead... which is an improvement in my opinion. (You can't watch hershey kisses in front of younger siblings... or at least, I wouldn't.) Multiple endings, too; although, it's fairly easy to see where the plot line branches.

Ace Attorney/Phoenix Wright series - The odd stab of humor, picking out logical fallacies in testomonies, and murder mysteries. Across at least 3 games.

Hotel Dusk: Room 215 - A VN by Cing, centered around a guy called Kyle Hyde. Solve the mystery of Hotel Dusk, and find out why it's relevant to Kyle's problems.
The Last Window: The secret of Cape West - Sequel to Room 215, more puzzles, picking up paperclips and interrogating people for information. Has references to the first game as well as one other game at least. ("I like suits, they're comfy and easy to wear!")

Professor Layton series - Don't be fooled by the cartoony graphics, some of these puzzles are real stumpers. Two games I can think of off the top of my head.

All games mentioned are available in English. They might not be VN enough for you, but you might enjoy them nonetheless.

Now, somebody tell me, does Sengoku Rance qualify as a VN? Never played it, but it's fairly heavy on the ol' hershey kisses, I've heard.
