So I just did some work to add a missing Manifestation Rule to Glitch's Zeroth tutorial and can I just say, that it's incredibly cool that I can just go "I want the player to be able to turn Glitch blue if they write the right program", copy 5 lines for one new rule duplicating an existing rule that ran during testing, write a test that writes such a program, fully integrated in my skein, and run the test and it just works, Glitch ends up blue.
Y'all, I wrote a game where you can change reality by programming.
I had honestly forgotten how cool that is.
