ABOUT THE STUDIO
Making games by testing how they feel firsthand.
WorksHub is where rin0420 publishes original browser games, web tools, and a Discord bot. Planning, design, development, testing, and updates after release are all handled independently. This page brings together information on the creator, the design approach, the published works, the articles, and how to get in touch, so feel free to use it as a table of contents.
Creator
Handle: rin0420. The focus is on browser games that can be played in short sessions and reveal more depth through repeated play. Alongside games, web tools that make small everyday tasks easier and a Discord bot are built with the same approach. Development history and source code are available on GitHub.
Design approach
The games prioritize responsive input, readable information, fair difficulty, and support for both keyboard and touch controls. Improvements continue after release based on play results and bug reports. The tools follow the same approach, aiming to reduce the number of steps needed for input and to make it clear to users how their saved data is used.
What this site publishes
WorksHub currently publishes twenty-one works in total: six games, eight web tools, two interactive exhibits, one Discord bot, two desktop apps, and two layout studies. The two desktop apps are for Windows 11 and are downloaded from GitHub; everything else requires no installation or account and can be used for free the moment you open it in a browser. Every work is planned, designed, and built independently by rin0420, not a reproduction of an existing title. The two layout studies are exercises in page structure, and every article shown in them is placeholder text.
Games
- VOID STRIKER: A vertical scrolling shooter about reading the paths of screen-filling bullets and making a series of quick decisions to slip through narrow gaps.
- WINDTRACE: A rally game that combines six cars with road surfaces of different character, including gravel, dirt, tarmac, and snow, racing for the best time on quiet mountain roads. It emphasizes not only speed but the rhythm of settling the car before the next corner.
- NEON WRAITH: A survival action game where automated weapons repel mechanical lifeforms closing in from every direction. Collect XP, shape your build, and defeat the GUARDIAN in all three sectors.
Web tools
- OVERKILL CALCULATOR: A calculator whose four basic operations are as accurate as any ordinary calculator, while the moment each result appears is accompanied by far more light, particle effects, and sound than necessary.
- FILTER BUBBLE LAB: An educational tool built around a fictional social network called “Flock,” where you experience how your own reactions gradually bias the recommended feed. Post-experience analysis and lessons help you think about how to engage with information.
- ASSET MANAGEMENT: A personal tool for checking asset accounts, income, expenses, unpaid card balances, and salary or fixed-cost schedules in one screen.
- SECRET MATCH: A tool where participants in the same place anonymously choose one person each, and a match is revealed only to the two who chose each other. It works by creating a room for up to 20 participants.
- PANTRY: A household tool that gathers food kept in the refrigerator, freezer, and pantry shelves so it can be checked in order of the nearest best-before date.
- GPUDB: A price history database that separates GPU models, retail products, and store offers so current prices can be compared with their history.
Discord Bot
The Asset Management Bot lets you manage assets, income, expenses, and plans through private menus in Discord. As with the web version of asset management, records are provided so that only the user themselves can view them.
Development notes and guides
The site publishes strategy guides based on firsthand play of the published games, an article explaining browser technology, articles on using the tools in everyday life, and development notes recording decisions made during production.
- VOID STRIKER Guide: How to choose between focused movement, grazing, and bombs as situations change, with decisions that support steady stage progress and scoring.
- WINDTRACE Guide: Lines and braking points planned backward from corner exits, and how differences between cars and surfaces should shape your inputs.
- NEON WRAITH Guide: Guidance on choices that lead toward weapon evolutions and movement that avoids encirclement, with an emphasis on recoverable early runs.
- How Browser Games Work: An introduction to rendering, input, collision detection, and saving, with short code examples.
- Building a Sustainable Budgeting Habit: Ways to reduce the burden of entry and establish a weekly review, along with precautions for ASSET MANAGEMENT's storage model.
- Managing Household Stock to Reduce Food Waste: Organizing household stock by location and date, with a practical PANTRY registration and stocktaking routine.
- Development Note: Tuning Shooter Difficulty: Notes on readable warnings, collision areas, and screen clarity that make failure understandable.
- Development Note: Local-First Design: Why ASSET MANAGEMENT and PANTRY initially chose localStorage, their later move to server storage, and the approach to backups.
VOID STRIKER also has its own detailed reference guide covering the enemy compendium, boss strategies, and credit system, along with a development blog recording implementation decisions. All articles can be read from the article index.
Available in Japanese and English
Every page on this site is provided in both Japanese and English. The language toggle in the top right of each page lets you switch the display language at any time, and the games, web tools, Discord bot, articles, and this about page are all available in both languages.
Where each work stores data
How data is stored differs by work, so each detail page states where it is stored. Games save settings and high scores in the browser's localStorage. OVERKILL CALCULATOR saves only the best combo count and does not handle names or contact details. ASSET MANAGEMENT (web version) and PANTRY store data on a Cloudflare D1 server managed by the operator. SECRET MATCH uses a Cloudflare Worker to operate its database, storing passphrases and participation tokens as hashes. The Asset Management Bot stores data in a SQLite database on the operator's PC and does not post records to regular Discord messages. FILTER BUBBLE LAB saves nothing at all; each session resets when the page reloads.
Transparency
Instructions, saved data, update details, and contact information are provided for each work. If advertising is introduced, ads will be separated from game controls, with no misleading presentation or rewards that encourage clicks. These principles will continue to apply as works are added or updated in the future.
Data handling and contact
Details on cookies, advertising delivery, and how each tool stores data are described in the Privacy Policy, and conditions of use are described in the Terms of Service. For bugs, display issues, or questions about published content, please use the contact page. As noted on the contact page, questions about products or services shown in an ad should be directed to the advertiser. When contacting us, including the name of the relevant work makes it easier to follow up.
