I’ve updated the license for all code downloadable from this site. The licensing terms can be read here.
In short, the code is licensed under MIT, so you can use it freely (unless otherwise stated specifically).
However, I need to protect myself and my collaborators, so all content (images, sounds, etc) is not licensed, so you may not distribute it or use it in other circumstances than to be able to build and run the code as provided here for educational purposes.
These terms should satisfy most visitors on this site 🙂
