Oh lol I just realized comment is because of my entry of this game into the NESDev Coding Competition 2022. I genuinely hope that not having a public demo available already wasn't considered untoward or inconsiderate, even if it technically doesn't break the rules.
I guess there's no real - reason - I couldn't just make the demo public right now instead of two days from now. But I also guess it wouldn't make a huge difference either way this early in the competition.
I'll resubmit after the demo goes live. This won't be my only entry. Thanks for checking in!
