Nº 003 — Action

Piyo's Adventure

Run, stomp, blast. Seven bosses including the Dark Priestess, and eight costumes that change how you fight. Five online leaderboards.

Soul Resonance ~Believe in Me~

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

Blocks crumble like sand; line up one color across a row to clear it. Two modes: Normal, where you compete for score, and Mindful, played without the clock.

Nº 005 — Puzzle

唯我独尊!十字熟語

  • Kanji Puzzle
  • Dress-up
  • iOS / Android
  • Japanese only
  • Free to play (planned)
  • In development

A puzzle where you find the kanji at the centre of four two-character words. The more you solve, the higher your rank and the more there is to wear.

Given 社□, 機□, □議 and □話, the answer is 会. 30–90 seconds a puzzle — one-handed and silent, even on a train. Images are from a build in development.

Nº 002 — Horror

14th Block Piyo's Night Walk

  • Horror
  • iOS / Android
  • Japanese / English
  • Free to Play

A side-scrolling 2D horror: spot the anomalies on a night street and make your way to Block 14. A red sky, flickering streetlights, a huge red moon — 41 anomalies in all.

遺失録 ―開かれない台帳―

  • Idealist SF Novel Game
  • Mobile and more (planned)
  • 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. Images are from a build in development.

Partner project

Planned and supervised by an outside partner; Veriquest takes on the system design, the development and the technical operation.

FPTI Diagnosis — Partner Project

  • Diagnosis
  • Web
  • Japanese

Where we build

01

Games

Online features like leaderboards and bestiaries are built in house too.

02

Study apps

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 — moving a shop's membership cards into an app (member card, points, notices), for instance. Drawing on experience in AI and DX from the concept stage, we work alongside you from sorting out requirements.

Commissioned development is taken on by System development; the examples are there too.

05

How we build

We build on web technology and ship native iOS / Android apps from one codebase.

  • TypeScript
  • React
  • HTML5 Canvas
  • Capacitor
  • iOS / Android
  • Firebase (Realtime Database / Cloud Firestore)
  • Cloudflare
  • RevenueCat
  • Sentry
  • Japanese / English
01

The work continues after launch

Fixing bugs and shipping the update are part of the build.

02

Bilingual from day one

Rather than bolting on a translation later, we design with the text pulled out.

About Works

Our motto: "turning ideas into things that run".

01

Formerly NullPo Works

Renamed from NullPo Works in 2026. The developer, the apps, and the support channel are unchanged.

02

The maker decides

How a game feels is decided by playing it as we build.

Frequently asked

01Do they cost anything?

All three live titles are free to play, with ads. Logica is planned to charge for some features.

02When can I play the Android version?

It is currently in closed testing; registered testers can install it from Google Play. See Become a tester.

03What do I do if I find a bug?

Let us know through the form below. Including the app name, your device, OS version, and the steps to reproduce it helps us find the cause faster.

04What happened to NullPo Works?

The name changed to Veriquest Works. The apps and the support channel continue unchanged.

05Can I commission software development?

Yes. A business system or app — moving a shop's membership cards into an app, for instance — is handled by Veriquest Systems (System development); the examples and the enquiry form are on that page. Website production is handled by Veriquest Studio.

06I have the idea and the expertise but cannot build it myself. Can we build it together?

Yes. As with FPTI Diagnosis in 03, the partner plans and supervises while Veriquest handles the system design, the development and the technical operation. The division of roles and the way of working are settled in the first meeting. Use "Development enquiry" in the form.
