I'm a huge fan of an old project called BulletML which was a way of describing shmup (typically bullet hell) patterns in a kinda weird and clunky XML format.I, however, think sexprs + a little lisp magic can make this idea a lot more fun so I made bullet-script.You can check out a live repl (ctrl+enter submits the buffer) + demo on the linked site in this submission and you can also check out a language guide here: https://bs.ell.dev/guide/I'd love to see what you folks can make! If you made a cool pattern please link and share it here!

Could you build this?
Yes A small Lisp-style interpreter, a browser REPL, a heatmap, and a basic dodge bot are all tractable for an AI-assisted solo builder working in a mainstream language.
