About me

yellowArrow.gif not found

I'm a front-end focussed game developer who is currently studying at HKU. (Hogeschool voor de Kunsten Utrecht) From a young age I've both played and made games, starting with Minecraft plugins in Java and now my own games from scratch in mostly Unity3D.
I'm a fan of simulation games, management games & strategy games and I dream of creating and publishing my own.

Town building simulator

This project was made for my finals exam at Alfa-college, I made this project to learn more about Finite State Machines & town building mechanics and balancing. While developing this project I learnt a lot about letting people playtest my game, balancing and AI. This game was made in Unity and got me my diploma for MBO game development.

This project was made as my test final Exam for my studies at Alfa-college, I challenged myself to make a space physics simulator where space enthousiasts who may play "Universe Sandbox2" and "Kerbal Space Program" let planets fall into eachother and launch spacecraft from said planets. By combining some of both games' features it makes for a fun and informative experience. Making this game was a huge challenge because of all the maths I was unfamiliar with, this game was made in Unity.

Comicbook Hero

This game was made in commision of Alfa-college and the Dutch Comics Museum, and was made to be played by young visitors of the museum between ages 8 and 14. To make this game appealing for the children to play, you play as a small child who gets trapped inside a comic book; and needs to find its way out. The 2D sidescroller-like gameplay makes it intuitive and easy for children to play. This game was made using Unity.

Noise Generator Tool

This is a tool I made to make custom noise textures based on parameters, the goal of making this was not for industry professionals to actually use it but to make a foundation to build upon to achieve that goal in the future. It's completely made with MVVM and scalability in mind and already offers some simple ways of generator some basic textures. It already features things like layers and different types of blend modes.
