Veriquest Works

Turning ideas into things that run.

Games, study apps, practical software. We plan, design, build, ship to the stores and run them ourselves, end to end. Three titles are currently live on iOS and Android.

An exhilarating side-scrolling action game: run, stomp, and blast enemies away. Dash from grassland to the deepest Depths and take on seven bosses, including the Dark Priestess.

Soul Resonance ~Believe in Me~

  • Color-Matching Puzzle
  • iOS / Android
  • Japanese / English
  • Free to Play

A fresh take on the falling-block puzzle: pieces crumble like sand, and lining up the same color across a row clears it. Chain three to trigger Fever Time. Comes with two modes — Normal, where you compete for score, and Mindful, for playing without the clock while you settle your mind.

遺失録 ―開かれない台帳―

  • Idealist SF Novel Game
  • Browser
  • Full Voice
  • Japanese only
  • In development

Whatever you wish for turns up at the university's lost-and-found window. In exchange, someone disappears — one at a time, and nobody notices even that. The story of a girl who keeps the records, and a man who does not disappear. An idealist SF novel game.

02Apps

Apps

Not only games. We build tools for learning with the same hands.

Nº A01 — Learning

Logica -A Logic Problem Set-

  • Learning
  • iOS / Android
  • Japanese / English

A problem-set app for learning logic systematically, from the basics to applications. Symbolizing conjunctions, disjunctions, conditionals and the like is practiced interactively, built around a "paper mode" where you work a proof out on paper first and check it step by step. In development with the goal of letting you study without a textbook.

Where we build

Works is not a games-only studio. What you play, what you learn from, and what you use at work all come from the same single skill: building software that runs.

01

Games

Three titles — puzzle, horror, action — planned, built, and run in house, online features like leaderboards and bestiaries included.

02

Study apps

Bringing the substance of a subject itself into the design. For Logica, we rebuilt the teaching order and the exercise format from scratch.

03

Practical apps

Tools to cut everyday hassle. A tax-filing assistant is one thing on the drawing board.

04

Business and DX software

Commissioned development for businesses. Drawing on experience involved in AI and DX projects from the concept stage, we work alongside you from sorting out requirements.

We take commissioned development enquiries too. Please start with Contact.

04Engineering

How we build

We build on web technology and ship as native iOS / Android apps. One codebase deploys to both platforms, so a small team can keep a lot of titles maintained.

  • TypeScript
  • React
  • HTML5 Canvas
  • Capacitor
  • iOS / Android
  • Cloud Firestore
  • Cloudflare
  • RevenueCat
  • Sentry
  • Japanese / English

The work continues after launch

Online features like leaderboards and achievements only really start once you ship. Receiving bug reports, fixing them, and pushing the update out are part of the job.

02

Bilingual from day one

All three live titles support Japanese and English. Rather than bolting on a translation later, we design with the text pulled out from the start.

06About

About Works

Veriquest Works is Veriquest's software development arm. Under the motto "turning ideas into things that run", we take a game or a tool as we first imagined it and deliver it actually working.

01

Formerly NullPo Works

The name changed from NullPo Works to Veriquest Works alongside incorporation in 2026. The team, the live apps, and the support channel all carried straight over.

02

The maker decides

Planning, design, implementation and operation are not separated. How a game feels can only be decided by playing it, never from a spec document.

07Support

Support & terms

How each app handles personal information, and its terms of service — the same documents listed on the stores.
