I love the basic premise. Not enough people? Crusade! Not enough food? Crusade! Not enough wood? Guess what, crusade!
I don't know if I was lucky, but I found it quite easy. I don't know if starving is the only way how to die, but to have enough food seems to be not an issue.
It would be nice to have some explanation about how much food is needed, is it that each day one person eats one food? If so, then the ability to sacrifice them (and thus decreasing the required amount of food) makes it rather easy.
I would very much like to play the more polished version with perhaps more features (which is of course over the possibilities in a gamejam) :-)
