They should add an ability that cleans units of status e.g. Immobilize, Poison and Jam. They can call it "Recover" or something. Also Valor seems useless without sweep and there aren't enough cards that can combine the two.
I found out you get eggs by using shovel on chicken, but I have no idea how to get milk. Using shovel on cows just makes fertilizer. Cooked things are pretty hard to make... I find it best to use all of your free time putting coal up that mountain so when you have "Bread + Cooked Meat" you have a fighting chance. I also seems like I just lose when I get to 34 points, I'm pretty sure I was still alive.
