Martijn Postma

Unity C# Developer, Game Producer

With 4+ years of professional game development experience, I bring ideas to market. I develop projects from concept to launch, with a focus on delivery speed and polish. By managing multidisciplinary teams of contractors I combine the differents facets of development into one neatly finished product. I've brought games to a variety of marketplaces and through Xbox One certification.

Kingdom: New Lands

2D Sidescrolling Castle Management Game

Kingdom is a 2D sidescrolling strategy/resource management hybrid with a minimalist feel wrapped in a beautiful, modern pixel art aesthetic. Play the role of a king or queen atop their horse and enter a procedurally generated realm primed to sustain a kingdom, then toss gold to peasants and turn them into your loyal subjects in order to make your kingdom flourish. Protect your domain at night from the greedy creatures looking to steal your coins and crown, and explore the nearby, mysterious forests to discover curious and cryptic artifacts to aid your kingdom.

I was contracted as a freelancer to port the Unity based game to Android and Xbox One Marketplaces while the main development team was working on the New Lands expansion. This involved developing custom certification features for Xbox such as user management, improving performance with platform specific solutions, and managing 90+ certification requirements with the publisher Raw Fury.

Viking Vishing

Free-to-play Score-attack Fishing Game

Out on the water, it's time to bring the fish home. Viking Vishing is a side-scrolling score-attack game for WebGL and Mobile. Fish will swim in from the sides of the screen. The player scores points by throwing the fish into the air and catching them with his boat. Not all fish are that easy however, the sharp teeth of a shark or the sting of a jellyfish will soon sink you!

For Viking Vishing I contracted a team consisting of a sound designer, visual artist and game designer. The inclusion of a designer allowed me to focus on development, team management and product management. The game was developed for the free-to-play web and mobile market. It features 7 different types of fish, unlockable boats with distinctive gameplay, and the sound effects are actual water.


Educational Object-oriented Programming Game

Remora is a game of programming, building, and exploring. It is about creating your own networks and solutions to problems. These networks consists of programmable robots acting and communicating together to achieve goals. One robot could move around searching for ore and, when it has found some, call another to come along and dig it up. Soon you could find yourself with a sprawling colony of self-sustaining artificial life.

Designed as an applied educational game, Remora aims to teach the user the mindset behind object-oriented programming. It uses a node based system with a simulated syntax, order of execution, classes and functions. Players can use mathematical operators, conditional statements and more to create anywhere from a simple timer to an automated patrol route.

Jolt, Cybersport

Screen-shared Competitive Mobile Multiplayer Game

Two player competitive action on a single device, welcome to Jolt: the cybersport of the future. In Jolt two players battle for victory in several arenas, scoring points by hitting the other with the Icosahedron Omni-shot. However, the sport will soon reveal that it has more tricks up its sleeve than simply throwing spheres at each other; make trick shots with the ricochet, activate force-fields and stay on the move. So grab your mobile device, an opponent, and get playing!

An independent production for which I worked closely with my contracted audio and visual artists. It uses the Unity NGUI asset for a mirrored player interface, with a design that accommodates limited touch inputs on older devices. The art style was designed to be easily readable on low resolution smartphones with camera movements that keep the player characters centered and away from the fingers operating the interface. The game was released to Android and Windows App Store marketplaces.
