Thank you, Malisa! I really appreciate your comments!
I agree that the streak system is slightly cryptic. As you mentioned, if you plant and harvest all your seeds in a day, your streak goes up. There are a couple sneaky ways the streak can die. If you accidentally plant two seeds on top of each other, you lose a seed and your streak ends. Also, if the marauder steals one of your bundles of wheat before you collect it, your streak ends.
Hope that makes sense. Thanks for playing!
