Q&A
Q1, What kind of game is it?
Noir Bunny Answer

A1, It’s a fun adventure game centered around exploration! Roam freely as your curiosity guides you, rediscover your sense of wonder, and enjoy investigating anything that catches your eye or any mysterious happenings you encounter! As you continue exploring, you may gradually begin to understand the secrets of this world. Solving the mystery is up to you… perhaps?

Q2, Are there any action elements?
Noir Bunny Answer

A2, There are a few light action elements in mini-games and certain gimmicks, but it’s not a high-difficulty or combat-focused game. It’s more about enjoying the world through exploration and gently stimulating your imagination and senses.

Q3, How long is the playtime?
Noir Bunny Answer

A3, With plenty of events prepared, it may take around 8–10 hours even if you move through it quickly. There are also replay elements and hidden events, so if you take your time, you can enjoy it for much longer!

Q4, Are there multiple endings?
Noir Bunny Answer

A4, Yes, there are! We can’t say too much, but if you put in the effort, something a little special might be waiting for you.

Q5, Can I enjoy it without knowing the original Alice story or retro culture?
Noir Bunny Answer

A5, Absolutely! Those are simply one of the elements within the game. If you’re familiar with them, you may gain a deeper appreciation, but we’d be just as happy if newcomers discover and enjoy them through this experience. We hope everyone explores together ♪

Q6, Is the story linear?
Noir Bunny Answer

A6, It’s a highly free-form game, so it’s not strictly linear. However, there are no irreversible missable elements, so you can explore wherever you like with peace of mind, expanding the world little by little at your own pace.

Q7, What is Noir Bunny?
Noir Bunny Answer

A7, We are residents scattered all throughout this world! Some of us may be hiding, and there might even be small settlements somewhere. We’re pure-hearted and curious, with all kinds among us! Though… a few can be a little scary, so be careful around those ones!

Q8, Are there missable elements?
Noir Bunny Answer

A8, Even after clearing the game, you can still experience all of its content, so don’t worry and enjoy playing!

Q9, How does the save system work?
Noir Bunny Answer

A9, The game supports autosave as a standard feature, and you can also manually save and manage your data using the typewriter in your room.

Interview

This project began three years ago, sparked by my “Alice” story originally created as a manga,

when I was approached by programmer Game Roman.

After creating retro game essays and facing setbacks with RPG Maker in my student days,

I poured everything into this work—the long-held desire to create a game of my own.


I deconstructed the story of Alice, then rebuilt it anew.

Blending elements such as dark fairy tale, Showa-era Japanese streets, retro games, internet memes, liminal spaces, and the Backrooms.

Cute yet unsettling, with a quiet sense of intrusion—I aimed for a “strange experience,” not splatter.


Alice is the origin of all my creations, a character I first conceived 16 years ago. I’m truly happy to finally share her with the world.

This world, mixed like a witch’s cauldron, gradually becomes one. Will you uncover the truth behind the unease?

Please experience this strange yet nostalgic world—and I hope you enjoy uncovering its hidden story.

Interview

When I received an offer from Game Roman—someone I’ve admired since my youth—I couldn’t help but exclaim, “Seriously!?”

Despite my background with ZUNTATA, I had never had the chance to compose for a game, making AIWU a long-awaited dream project.


I was given a great deal of creative freedom, and even introduced many new sound sources in pursuit of the ideal sound (laughs).

Each track is crafted with care and soul—please enjoy every detail.
