hmm.. that video was a good walkthrough 🙂 one thing I noticed is that the gain-an-ingredient page has 33 items there? since everything's on a 4-hour timer, I can only run it 28 times normally (although someone who can stay up over 16 hours straight and always do it on time could get up to 35). I'm not actually going to get all of them, then (and since the gem reward is 10 and it costs 20 gems to refresh sooner, it's probably not worth rushing it).
also, the random-on-random nature of the game is even clearer now. every 4h you get a random ingredient (or other item), and then your collection of ingredients gets tossed onto the board at random, and all you get to control is when it stops. :/ this feels very un-diggy-ish to me.
