Mind Hole is a short psychological horror game entirely developed by a single person, Kazumi404.
What started as a simple test while learning RPG Maker MV gradually grew into a personal, atmospheric project shaped by music, trauma, and surreal tension.

🌑 What is Mind Hole?
You play as Rui, a young woman living in complete isolation after traumatic events in her past.
Confined to her apartment, she spends her days in silence, until her nights begin to change.
Her world has shrunk to a single room, quiet, familiar, and suffocating.
But lately, her nights have changed.
Sleep becomes a battlefield.
Something refuses to let her rest… and it’s getting harder to ignore.
Mind Hole mixes psychological horror, puzzles, and story-driven mystery, drawing inspiration from AntiHoney ’s music and the real phenomenon of sleep paralysis (金縛り / kanashibari).

👁️Characters Inspired Directly by AntiHoney
Every character in Mind Hole is 100% inspired by the lyrics of a specific AntiHoney song.
This is antihoney's official website.
Their personalities, motives, symbolism, and emotional “lore” come directly from the themes expressed in those original lyrics.
Instead of creating characters first and searching for meaning later, Mind Hole does the opposite:
their entire existence is born from the music.
The songs are the foundation, and the game is the interpretation.
This creates a surreal atmosphere where emotions, fears, and illusions feel like they came straight from a dream, or a nightmare.
The project is old, and I received written permission from AntiHoney herself before she passed away, allowing me to use her work as inspiration.
The game has no commercial intent regarding her music, it was created out of admiration and respect for what she made.
In many ways, Mind Hole is a tribute to her art.
The songs are the foundation, and the game is my way of interpreting and honoring them.
🧩Gameplay & World
Mind Hole takes place entirely inside Rui’s apartment, turning one familiar space into a layered psychological maze.
Through small interactions, puzzles, and daily routines, you uncover pieces of Rui’s reality… or her mind.
Features
Characters whose lore is directly based on AntiHoney’s lyrics
Multiple endings, each revealing different interpretations
Puzzle elements woven into daily interactions
Voice acting for deeper immersion

📜 Official Disclaimer
"Mind Hole" is a non-commercial, personal project created by Kazumi404 as a tribute to the musical legacy of AntiHoney.
About the Soundtrack: All music used in this game is the original work of the late singer/songwriter AntiHoney. This project was developed out of deep admiration for her art, and I received personal permission from her to use her work as inspiration before her passing.
A Tribute to Her Voice: My main goal is to ensure that AntiHoney’s hauntingly beautiful music continues to be heard and that her legacy is never forgotten.
Supporting the Artist: This game is 100% free to play. While donations are enabled on this page, they are entirely optional and go directly toward supporting my work as an independent artist (development, art, and programming). No profit is being made from the distribution of AntiHoney’s music itself.
Visual Inspiration: The visual identity of our protagonist, Rui, is also a dual tribute, inspired by the aesthetics of both the musician AntiHoney and the talented artist Anti-Honey from DeviantArt. Her profile: https://www.deviantart.com/anti-honey

Hey everyone ❤️ Happy new year! I wanted to give you a clear update on how things are going this year.
💸 First of all: Commissions 💸
I’ll be reducing my slots a lot. They’ll be mainly for friends and people I already know, and when I do open to the public, it’ll be 1 to 3 slots MAX. This is because I’m currently working on two large game projects, and I really need to protect my time and energy.
Because of that (and finally having space to breathe), I’m also getting back to my personal projects:
⛈️ Weather Child ⛈️
The script is fully revised
Sketches are already done in my notebook
I’ll be updating it for Patreons
🔗 LINKS: https://linktr.ee/weatherchild
👻 NEW PROJECT! (not too new...) 👻 Animal Crossing Diary
This is a very old project I finally started posting! It leans into horror, built from things that actually happened in my game... I always play games by digging into their lore and creating my own story, especially games that are more open-ended.
Chapter 1 is live, and everything is finished — I’ll just be releasing it gradually

🎮 Old Short Game Project is back! 🎮 MIND HOLE
I’ve resumed work on a very old short game of mine. The itch.io page is already up. Take a look!
🔗 LINK: https://kazumi-404.itch.io/mindhole
Everything I’m talking about here is already done or in motion, no vague plans this time, just results.
Thank you so much to everyone who’s still here and supporting me 🖤
2026 has everything to be an amazing year, and I still have more surprises coming ✨
Hoi~! I'm Kazumi404, Brazilian generalist artist, indie developer and junior art director with over 10 years of experience creating original projects across comics and games.
I have a LOT of imagination and MANY dreams to pursue.
I love space, monsters, horror, gore, sci-fi, drama, nonsense, psychedelic and cute things. Whenever possible, I blend these elements into my stories and creations, often mixing contrasts to build unique visual identities.
I work mostly with horror, slice of life, Sci-fi, psychological themes and emotionally messy characters.
I LOVE cute, creepy and psychodelic visuals
I create original projects and also make frequent fanart.
