I've been thinking about writing some kind of little games for years. Back in 2016, I actually created a repository, but only ever got as far creating a README. I've finally been spurred into action by Ron Jeffries' lovely series of articles describing his journey writing a version of Asteroids for iPads. They are just full of coding pleasure, so many thanks go to him.
Thanks also to Jeff Minter. I've been a fan of his work since I was 14 or 15 years old, and it continues to be a joy. If I can capture a tiny, tiny part of what makes his games so wonderful, well, that'd just be fantastic.
