For me, on a 2021 MacBook Pro M1 Max, on MacOs 15.1.1, it appears to work in Chrome but in Firefox shows this error.
error: script:16:1: compile error: unknown symbol twist
in evaluate [lib/evaluator.janet] on line 81, column 7
in bauble-evaluator/evaluate [lib/init.janet] on line 8, column 12
delete the contents of the script and then refresh — you’ve loaded an old version of bauble before and have the old tutorial cached in localStorage :/
