Sumico
Did we just create an entertainment math game? Yes we did! And it is super addictive, too. It’s going to be out on iOS and Android soon. So I can’t reveal too many details just yet. But you can have look at the game’s official website. Sumico is a collaboration between Matthijs Dierckx and my company Ludomotion.

Bezircle
Bezircle is the game I've been working on hard with my company Ludomotion. It's currently available for iOS. It features skillful, multiplayer gameplay with a single button control-scheme, and offers a condensed strategic experience in levels that last only two minutes or less. The basic game mechanics are accessible and elegant, yet simple variations create depth of play that will take some time to master. All the art assets in the game are hand painted and lovingly animated. The game's visual style and attention for detail sets it apart from most games built for the same budget. Nobody can play Bezircle and not feel the love that went into its creation.

Dules
Dules is going to be a free-to-play tactical multiplayer online shooter, with a cutting-edge generation system that will guarantee a unique experience for every mission. The game is currently under development. At this time, it contains multiplayer gameplay, configurable vehicles and millions of worlds. We are moving rapidly towards a public beta, that will last for about one year. During this beta period, development will continue, which means that the game will be expanded with new types of missions, enemies, weapons, and other extraordinary modules.

Game Mechanics
Game mechanics are the rules, processes, and data at the heart of a game. They define how play progresses, what happens when, and what conditions determine victory or defeat. Now two leading authorities in game design–Ernest Adams and Joris Dormans–are here to teach game designers and students alike the essentials of game mechanics.

Machinations: Game Mechanics Diagrams
Feedback loops play a vital role in emergent behavior in games. To understand a game’s feedback loops is to understand a game’s dynamic gameplay. However, observing and documenting feedback in games is not as easy it seems. In an attempt to solve this problem I have created a Flash tool to create interactive and animated feedback diagrams (after this possibility was suggested to me by Stéphane Bura). Currently the tool has been upgraded to version 4.0. This latest version is released to accompany the book on game mechanics Ernest Adams and I wrote using the tool and the framework.

Engineering Emergence
My PhD dissertation (pdf, 18MB) is finished! It sets out to develop formal tools for the hard task of designing games. Games, as rule based systems, often display emergent behavior. One of the core aspects of games, gameplay is often considered an emergent property of game rules.

Flix 2
Flix 2 is a comical, but challenging, platformer where you play Flix: half blob, half spider. You can jump, roll up steep hills, stick to ceilings, and use your grappling arm to swing through the levels of this skill based game. Collect stars to open the exit to the next level while avoiding traps and enemies.

Geth2o
Geth2o is a serious game concept I worked on for Butterfly Works. It is a game about living in the 'informal settlements' in Kenya. I worked out the rules for a board game simulating the struggle for survival, and they have translated that into a game for the mobile phone. Both the board game and the mobile game are going to be put on the market. Have a look at the game's official site. (I've never had a prototype being flown to Africa for a focus group test).

Campagne
Finally it's there! Our satirical card game of the upcoming Dutch elections. In this game you take control of a party, recruit candidates, control the news and sling some mud at the competition. All in the best interest of the country, off course… Check out the website (which is in Dutch).

Seasons
Seasons is a slow paced action platformer about the power of imagination and storytelling. Restore the world to its former glory by reliving the past. Part experiment in game design, part experiment in storytelling. Enjoy!

Flix
Find enough orange stars and help Flix escape to the next level in my latest game. Flix is a sticky, bouncy platformer with soft body physics. A result of an experiment with Verlet integration, that grew out of control. It is also my largest Flash game to date. Go and find the secret mini game!

Dungeon Run
Collect minutes to score points in this fast paced little adventure game, which really started out as an example for a new educational game library I have been working on. Inspiration for this game come from Zelda and the Atari Adventure game mostly (yes, I've been reading Nick Montfort and Ian Bogost's new book, but more about that later).

Ascent
Reach the target altitude by jumping, flying and pushing your way up through this futuristic little platformer drawn only with rectangles. If I write another graphics.drawRect command I will scream. This is what I could code in a single weekend and a bit.
As a bonus option you can play the first prototype here (You might be interested in the similarities differences). It is the stage of the game after about three or four hours.

Phat Man
I just finished a quick experiment with Flash inspired by Steve Swinks's book Game Feel. It is twisted version of Pac Man. It is also my first experiment with MochiAds, so you'll have to sit through a commercial to play this one. Sorry about that.

Workshop Games of Emergence
How to design emergent gameplay was the topic of a workshop my colleague Remco van Swieten and I recently ran for the Dutch chapter of the Digital Games Research Association (Digra). The idea was to visualize feedback structures within the game system and to design the game and its emergent gameplay from there. The workshop was based on my recent presentation and paper on visualizing game mechanics. Although this was no easy task, I got the impression that all the participants enjoyed the workshop.

Regel Jij Het Even
Translates as “You Deal With It” and is a small internet game I developed for the city of Amsterdam. The explanation is all in Dutch, but the game is pretty straight forward. You need to react to the signals produced by the citizens of Amsterdam by catching them with the right desks. You can drag around the desks for this purpose. You will notice that your performance will improve when you think about the organisation of the desks as a whole and refrain from micro-managing.

This game is tested in IE6, IE7 and Firefox. On older machines it runs best in IE6. Follow this link to play the game...

Colours
In this little game the player needs to collect and redistribute colours. The game world starts out grey and colourless. By finding and returning the right colours you can restore this world. It is a brief experiment in game design with an altrustic and aesthetic effect.

Shadowcaster Taking Shape
Shadowcaster, a game project of Jasper Rijnbout and myself, is slowly taking shape. We are currently working on the level that will function as the game's engine test, demo and prelude. A few screenshots give you an idea of what is to come...

Kapitein & Co
Captain & Co (as the English translation reads) is a small internet trading game I am designing. It will accompany the educational site Zeeopschool.nl ('sea-at-school'), which tracks a small freighter called the Lida that travels the world's oceans. The game's concept is that children who visit the site regularly can command their own ship. This virtual ship visits the same locations as the Lida does, and traverses the oceans under the same circumstances. The game takes the real-life input of weather conditions and location to generate events in the game.
