Publisher PLAYISM will developers illuCalab and WSS playground-have delayed science-fiction mystery adventure game EDEN.schemata(); from its previously planned 2024 release window to 2025. It will be available for PC via Steam with English, Japanese, and Simplified Chinese language support.

Here is an overview of the game, via its Steam page:

About

EDEN.schemata(); is a multi-ending sci-fi mystery adventure game, featuring headless corpses, a sealed laboratory, a limbless android suspect/heroine, and an amnesiac protagonist. The game design and gradually UI change in reflection of your actions. The steampunk-style artwork and the character animations were all handled by a single animator.

Story

“Nice to meet you… again?” An android named “Eve” speaks to “you,” before a headless corpse apparently known as “The Professor.” Completely devoid of any sort of memory, “you,”　together with “Eve”—an android, and the Professor’s apparent killer—must uncover the truth of what really happened here. Use your powers of deduction to unravel the mystery of this sealed laboratory, one revelation after another. We hope you enjoy this all-new type of mystery – the kind that’s only possible with video games.

Characters Depicted in Beautiful Hand-Drawn Animation

The Main Character – Has no idea who they are due to total amnesia. Somewhat unreliable.

Eve – An android. As the main character regains consciousness, Eve is standing before the corpse of “the Professor”. The heroine, and also the prime suspect.

The Professor – Eve’s creator. Found as a headless corpse upon the main character’s awakening.

Kel – An integrated discipline interface. Something like an AI that punishes people for their crimes, but which for some reason speaks like a little girl and can be quite agitating.

User Interface and Game Design that Change Along with Game Progress

The user interface and game design in general change in accordance with your game progress. The story and UI come together, and the general game design gradually transforms, providing an all-new, almost magic trick-like game experience.

Main Staff and Comments

Scenario: Van Madoy (known for Revoir series, “Murder at Kogetsukan” in Fate/Grand Order) – At the beginning of the project, I thought, “Is there even anything left for me to do in the world of mystery games that my predecessors haven’t already done themselves?” However, as development progressed, I reconsidered and thought, “Maybe I can realize the ideal mystery via the medium of video games.” The concept of this game is “a mystery that can be solved over and over again.” I hope you enjoy the experience of solving the kind of mystery that is only possible with video games—one that’s sort of different from other “multi-ending” games.

Direction / Development: EIKI’ (known for GENSOU Skydrift, Living in the Ending World) – I consider the adventure genre to actually be a no-rules, cross-species battle. We bring you an all-new breakthrough adventure worthy of its striking visuals and writing.

Character Design / Animation: Yutaro (known for Touhou Tegaki, Touhou Youyoumu: The Maximum Moving About) – What’s the point of using hand-drawn animation to express characters in games, especially in adventure-style stand-up fashion? Well, I’d like to give any answer other than “This is the only way I can!,” so let’s say it’s that I’m striving to depict my art in a way that shows the pleasure and rawness of animation in an adventurelayout.

Sound: RD-Sounds (Diao Ye Zong) (known for “Sacrament (Vatican Miracle Examiner ED),” “Absolute One-way Street ~Unreachable Message~ (Touhou Project Arrangement Track)”) – A story is, after all, a combination of pictures, sounds, and stories. Game scenes, controls, background music, sound effects, story, visuals… I want to find out just what I can do using sound to fuse all of these elements together in order to tell a “story” in a game.

About

EDEN.schemata(); is a science-fiction mystery adventure game produced by WSS playground, also known for games such as Needy Streamer Overload. You start the game in a locked laboratory, where an android named Eve talks to you and you both notice the headless corpse called the “Professor” at your feet. You don’t remember anything, and Eve is the prime suspect for the murder, but you’ll have to work together to solve the case. The beginning sounds like any orthodox adventure game, but the more you play, the more you’ll learn about the truth, and the game’s user interface and game design changes as you progress, until you reach one of multiple endings.

The team behind this game consists of:

The developer EIKI’ from illuCalab., known for many other games such as GENSOU Skydrift, Living in the Ending World, and Takkoman.

The writer Van Madoy, known for the Revoir novel series and “Murder at Kogetsukan” (Fate/Grand Order).

The character designer and animator Yutaro, known for creating hand-drawn Touhou Project fan animations for over a decade.

The sound producer RD, known for “Sacrament” (Vatican Miracle Examiner ending theme) and Touhou Project arrangements.

The Story

“Nice to meet you… again?” An android named Eve speaks to you, in front of a headless corpse apparently known as “the Professor.” Completely devoid of any sort of memory, you and Eve—an android and the Professor’s apparent killer—must uncover the truth of what really happened here. Use your powers of deduction to unravel the mystery of this locked laboratory, revealing one truth after another. We hope you enjoy this all-new type of mystery—the kind that’s only possible in a video game.

Ever-Changing User Interface Design

At first, it’s a simple point-and-click adventure game where you use keywords to progress the story, but the user interface and game design in general will actually change in accordance with your game progress. The story and user interface work together as the general game design gradually transforms, providing a brand new, almost magic trick-like game experience.

A Story that Unfolds through Multiple Playthroughs

This game has a “skip” function, but not a “save” function. The story loops and branches off constantly with every playthrough, and there are multiple endings for you to uncover.

Entirely Hand-Drawn Original Animation

The steampunk-style artwork and the character animations present throughout the game are entirely hand-drawn by a single animator, Yutaro. Simply observing the animations and watching Eve come to life is a breathtaking experience in of itself.

Word from the Developer

Even us developers are facing all sorts of new experiences and challenges every day making this game, but we’re having a lot of fun. Please wait a little longer until it’s finished!
