When teaching game design, I often had a need for simple game editors that would allow my students to explore different game design concepts. It was very difficult to find suitable tools that fulfilled the following criteria:
* easy-to-learn
* available for Windows, MacOS and ideally Linux
* free

As I am also regularly supervising student projects, I decided to have students create these tools, so that other students would then benefit from them. You can find all “Game Design Games” on an itch.io page.
