At first I had a really hard time with this game and didn't understand it at all.
Then I came back to it and actually did understand it (mostly).
I recorded my first play session, which will probably be a bit frustrating for you to watch, but perhaps it's also illuminating since I'm narrating my thought process. I'll leave more feedback in the jury form, too, with reflections after my second playthrough where I understood enough to complete all levels.
