...I would appreciate an advice.

I started the game a couple of times, and each time all of my villagers would weaken and die during the time between, I think, 2nd and 3rd crop harvesting. And, obviously, I wouldn't want to see that happen again.

So, I was wondering...I have puzzles 1-4 and 8 complete, and 5 is on the way. My village has seven people, five adults, one child and one baby. I had previously bought level 2 for farming and spirituality. What is the next thing I should buy? Waiting for the level 3 of farming seems like a long way to go.

Also, any other economy-unrelated tips to escape this err...genocyde would be more thank helpful:)
