Due to me wanting to keep the buttons so close, it had to be "almost" tileable (with 1-block of space gap).
Unfortunately I didn't take a screenshot of the 2-Block swapper.
It was a fun time, like 2 hours total, going from "This works", to "What if I make it better", testing timmings, and trying to make it compact. I'd be glad to see any suggestions
