Game development

Games and interactive apps, built in Unity.

I develop games under my own studio, 1Time Games, and build serious games, training tools and interactive 3D applications for businesses. The same experience, put to work for your goals.

01/Services

What I build for you

  • Serious games

    Games with a purpose: to train, teach or get a message across in a way that sticks.

  • 3D configurators

    Let customers build and view your product in 3D, in the browser or as an app.

  • Interactive apps

    Presentations, trade show applications and visualizations that people can explore on their own.

  • Games for PC and mobile

    From prototype to release on Steam or in the app stores, including analytics and updates.

02/1Time Games

My own game studio

Under the name 1Time Games, I develop my own titles. That's where everything comes together: gameplay and AI in Unity, plus the website, wiki and analytics platform around it.

Nederfall

Survival management, the Netherlands 2040

Nederfall

A post-apocalyptic colony sim where you lead a camp of survivors and send soldiers on raids across a collapsed Netherlands. The survivors live their own lives while you direct the raids.

  • Unity 6 and C#
  • Playable in Dutch, English and German
  • Windows, macOS and Linux
  • Dedicated website, wiki and analytics

In development

The Playtester

“Perform badly and the next human wakes up in your room.”

03/Approach

Why Unity

  • One project, many platforms

    PC, Mac, mobile, web and VR from the same project.

  • Proven technology

    Unity is one of the most widely used engines for games and interactive applications.

  • From game to backend

    Along with the game itself, I build the website, integrations and analytics around it.

  • Fast iteration

    A playable prototype quickly shows you whether an idea works, before you invest in full production.

05/Frequently asked questions

Good to know

What is a serious game?

A game that teaches or trains something while it entertains. Think safety training, onboarding new employees or educational material.

Can a game run in the browser?

Yes. Unity can export to WebGL, so a game or configurator runs right in the browser, with nothing to install.

What does a game cost?

A playable Unity prototype starts at €2,950. A small game, serious game or configurator starts at €7,500. Larger productions get a custom quote.

Do you also work on existing Unity projects?

Definitely. I can join a project already in progress, for example for gameplay programming, tools or connecting a backend.
