Welcome to the official portal of my creative projects. Here, you will find a diverse range of products developed with a focus on engaging, casual gaming experiences for all ages.
As a solo developer, I am often balancing multiple stages of production simultaneously. While this means devlogs and updates may be infrequent, my commitment to quality remains my top priority. I hope you find these projects as enjoyable to play as they were to build.
To support my work and ensure your own digital safety, please only acquire my games through the official links provided here. I cannot offer technical support for versions found on unauthorized third-party sites, as these are distributed without my permission and may pose security risks. Thank you for supporting independent development!
All of my mobile projects are hosted officially on the Google Play Store. You can jump straight to my developer page by clicking the icon.
My goal as a developer is to explore various genres rather than sticking to just one style. I aim to create experiences that cater to as wide an audience as possible, though you will occasionally find specialized projects designed for specific age groups or interests.
I maintain a dedicated blog on Blogger.com for my ad-supported applications. These versions follow specific third-party provider guidelines and offer the same core information as this site, but with a focus on free-to-play content. You can access the blog by clicking the icon.
Status Note : Please be aware that as of 2023, all ad-supported applications have been discontinued due to technical complications. While these versions are currently offline, I am exploring the possibility of reviving them in the future.
Beyond my mobile games, I host a variety of base projects, and flashcards on itch.io. This platform allows me to share work in formats that aren't supported by the Google Play Store.
The content on itch.io aren't apps. I keep these distributions separate to respect the unique guidelines of each store and to provide the best experience for different types of users.
For a look at some of my recent project showcases and custom wallpaper designs, please visit my Opera GX portfolio. My wallpapers are optimized for Windows and may be compatible with other operating systems as well.
Note on Updates : As of 2023, I have paused expansion of this collection. Currently, monetization features on the platform are limited to a select group of contributors, making it difficult to offset production costs for new GX-exclusive content. While the current collection remains available for you to enjoy, future updates will depend on the platform's support for independent creators.
My app splash screen, watermark, web portal, and blog may either show all, any of these names, or any combination of it.
While I have operated under the handle Prectorian since 2001, PRECTORIAN SOLO PRODUCTION was officially established in 2018.
As the name implies, this is a dedicated solo effort focused on developing applications for the Android OS, exploring various digital platforms, and creating unique digital products.
You may see projects or logos featuring the name KOUKI, which I adopted as an alternative handle between 2019 and mid-2023.
KOUKI is rooted in two Japanese Kanji characters that represent my approach to development:
興 (Kyō): Meaning "excitement" or "interest."
起 (Ki): Meaning "to stir," "to wake," or "to initiate."
Together, they represent the drive to initiate excitement through my work.
The insect logo variations shown serve as a tribute to my late father, who was an entomologist. Using these designs is my way of honoring his legacy and his passion for the natural world while I build my own digital ones.
Since July 13th, 2023, I have adopted the handle DOCODEMO.
The name is a Japanese term meaning "Wherever and Whenever."
It reflects my goal of creating accessible, engaging digital experiences that you can take with you and enjoy at any time. The logo design (shown) represents this new era of my production, focusing on versatility and modern casual gaming.
As of March 16th, 2026, I have transitioned to the handle URUSHIN. The name is composed of two Japanese Kanji characters that define my professional philosophy:
売る (Uru): "To sell" — representing the commercial life of my products.
信 (Shin): "Trust" or "Faith" — representing the integrity and reliability I offer to every user.
URUSHIN is more than just a name; it is a commitment to my supporters. It signifies that when you acquire a product from me, you are receiving a work built on a foundation of mutual trust and quality.
