How do you define an "adventure" game then ? It tells nothing about the gameplay. Saying it's "adventure" is like saying it is "murder mystery", "romance" or even "horror", it can be used for a game, book, and movie, why not for a VN ?

true , not even game

From the screenshots, I see:
* Spiritual E. represented as both a meter and a figure; seems 100 is the maximum.
* Action points, on a screen where you can select a location to visit. (This is also one of the screenshot with Spiritual E..)

Those seem at least a little game-like to me. When I define genres, I like to look at gameplay aspects that are not present in games I would not consider to be in that genre.

To me, an adventure game is characterized by scripted puzzles. A simple example of such a puzzle is to take an item and use it in a specific spot; more complex puzzles exist. What differentiates adventure from puzzle is that, in a puzzle game, the game has a simple set of rules that can create emergent behavior, while in an adventure game puzzles are scripted.

(For the "adventure" genre, I want it to include games like Colossal Cave, while "puzzle" I expect games like Bejeweled and Tetris to qualify.)

(It's not impossible for a game to have both; I saw a "trailer" for an adventure game on GOG that went through an early-game puzzle, and it did at one point have a puzzle-game style puzzle in it.)

(Note that most "action adventure" games aren't really adventure games by this definition, or only have light adventure game elements; La-Mulana is an exception, as its adventure game elements are prominent and hardcore.)

if anyone has played it - how much of an actual gameplay (e.g choices and other interactive elements. I see some hub that implies light rpg elements) is there, on the scale between Planetarian and Long Live the Queen?

Even if I had played it, I wouldn't be able to answer, as I have not even heard of either Planetarian or Long Live the Queen.

We call those "quests" or "puzzles" where I'm at, depending on whether it's a story with puzzle mechanics, or largely self-sufficient as a puzzle. Adventures, in my book, are exploration in interactive environment, with story matching the criteria of literary genre by same name. It might have puzzles, it might not, it might use mouse or keyboard or gamepad, it might use physics or be completely text based, all of that is secondary, really. And of course all three blend often enough out there.

Not region blockend AND no Unrated DLC? One of those facts seems to be false at the moment I think.

Looks interesting as there's much more interactivity to the usual VN genre, wishlisted!

This is an all-ages title. There is no adult content.

Ah, thanks. Would not have suspected that. That's fine with me.

Thank you so much for the release!
Glad to see anything from the Minato brands (and fingers crossed for Majikoi to come here next!). Didn't know they did all-ages releases, and this one looks fun :D

As far as whether this should have the "adventure game" label or not... it seems to have the main hallmarks of one - interactive story, choosing locations to move between/exploration, gathering things that then influence the outcome. Unsure about whether it has puzzles though - which is part of the definition of "adventure game", but what counts as a puzzle exactly? Pretty sure I've also played adventure games that didn't have (or had a very loose definition of) puzzles, so idk. Hopefully someone with more knowledge of the game can elaborate on that front :P

But my point is... VNs can definitely be adventure games. Just as you can have other genres cross over. Whether this one specifically fits the label or not, I'm not sure, but I have no idea how you could say that Zero Escape series and Danganronpa series, among many others, aren't both adventure games and VNs at the same time. =_=

But does this game have puzzles? Do you actually have "investigation gameplay"? Like Snatcher, for example?
