I've just released fully documented source code for The Sentinel as an easy-to-browse website.
It's a lot more fun to explore than the GitHub repository, with cross-references, popups, indexes, statistics and more.
Enjoy!

John Carpenter on making the music for "Sentinel Returns":
![I'd love to, and I did a video game back in the 90s. It was Sentinel Returns. I was shooting a movie [1998’s Vampires] in New Mexico and they asked me to do the music. I went to a studio one Sunday, my day off, and just knocked out something and gave it to them.
They seemed happy, so, fine. I never saw the game. Nobody told me how it was, I don’t know anything. No one tells me anything!](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:ucwjleevh3u7yq4safl6dnsa/bafkreihxnyj3bwryvb6jc7sg3rky7nfg5wdzuuo4q4zckjic7uxibxwgge@jpeg)

When I converted the ZX81 game last month, it was 8.5K. It should be easy to fit that into 8K, right?
Lots of things you can do to make your BASIC programs smaller, faster (and less readable).
