Vie. Designing games is complex and time-consuming. To accelerate and simplify the process, we have developed the Vie app, now available for download. Vie is a powerful game creation tool for rapid 2D game prototyping and playtesting.

Mini Game Jam. We have designed a beginner-friendly tutorial that makes learning how to code more fun, visual and accessible for everyone. At the CWI Open Day in 2023 and 2024, children aged 8 to 14 participated in this tutorial to explore the world of game design.

We use Machinations to express game economies (rules) as “marble machines” inside running prototypes. Choose from two exciting themes: a) Help find a lost bunny, or b) Save the world by preventing climate change. After a short demo, you can create your own game rules and instantly see your ideas come to life. To get you started, we’ve included assignments and a handy cheat sheet, and a demo movie for a step-by-step guide.
