EDEN.schemata();

About this game

EDEN.schemata(); is a multi-ending sci-fi mystery adventure game, featuring a headless corpse, a sealed laboratory, a limbless android heroine (and the main suspect), and an amnesiac protagonist. The game design and UI change gradually in reflection of your actions.

The steampunk-style artwork and the character animations are all hand-drawn 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 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.

Characters depicted in beautiful hand-drawn animation

You (The Protagonist)

Has no idea who they are due to 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 protagonist’s awakening.

Cherry

An integrated discipline interface. An AI that punishes people for their crimes, but also speaks like a little girl for some reason. Can be infuriating.

UI and game design that change along with game progress

The UI and game design in general will change in accordance with your game progress.

The story and UI work together as the general game design gradually transforms, providing a brand new, almost magic trick-like game experience.

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.

I consider the “ADV” genre to actually be a no-rules, cross-species battle. We bring you an all-new breakthrough ADV worthy of its striking visuals and writing.

  What's the point of using hand-drawn animation to express characters in games, especially in ADV-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 ADV layout.

  A story is, after all, a combination of pictures, sounds, and stories.
  Game scenes, controls, background music, SFX, 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.

  Announcement: Release Date Change for EDEN.schemata();

  We had originally planned to release EDEN.schemata(); this winter.However, in order to further refine one of the game’s cores “narrative and gameplay flow that changes based on the player’s actions,” we have decided to adjust the release window to a planned launch of 2026.We sincerely apologize to everyone who has been looking forward to the game.The development team is working with the utmost dedication to deliver an even better experience. ■ A Letter from the DevelopersTo everyone who has been waiting for this game, we are truly sorry.The release date has been moved to “2026.” We apologize for keeping you waiting yet again. The support we’ve received, from the excitement voiced across various communities to the feedback from players who tried the demo at events, has been a tremendous source of encouragement for our team. We are deeply grateful. This project involves implementing an unusual system into the game. We believe this system will make the experience truly one-of-a-kind, but such an ambitious approach also presents significant challenges.There were moments when we wondered if perhaps creating a game like this was too early for us—or even for humanity—but after much trial and error, the final vision is gradually taking shape. Because we want to present the game at its best, we kindly ask for a little more time. Additionally, because of how the game plays, the UI, and story all change based on the player’s actions. Which means even sharing small bits of information becomes potential spoilers. This has made it difficult to communicate ongoing progress through social media, even though development is continuing steadily each day under director EIKI. We are eagerly looking forward to the day when we can share this game with all of you, and we hope you will look forward to it as well. Your patience would mean the world to us. Thank you once again for your continued support of EDEN.schemata();.

  EDEN.schemata(); Joining Tokyo Game Dungeon. Publisher & Release Date Changes

  Hello everyone, Thank you for your continued support of EDEN.schemata();. We would like to inform you that the publisher for this title has been changed to Alliance Arts. While we had initially aimed for a Spring 2025 release, we have decided to shift the release window to Winter in order to further refine the game. EDEN.schemata(); was originally scheduled to participate in the February 2025 Steam Next Fest, but after careful consideration, we believe it is best to let players experience the game once it has reached a more complete state. We sincerely apologize for the extended wait and greatly appreciate your continued patience. At the same time, the development team is eager to receive feedback from players. To that end, we will be exhibiting EDEN.schemata(); at the upcoming live indie event, Tokyo Game Dungeon.
