This is a really fun box. The bread crumbs are there all the way through. It does help to write some code that you can run locally for the foothold to understand whats actually happening. I’m a newb with the last bit of technology and thanks to @TazWake for a few nudges realized you need to make more than one change to get up.
Extremely well designed. Thanks @xct and @jkr for building the fun.
