Interesting, this one. The day/night cycle felt REALLY aggressive, but I think that was the point, to generate a sense of urgency to get supplies and preparations done quickly.
I sadly have to echo the sentiments of the others with being confused as to what to do. I understand the time constraints of the jam and scope creep perhaps getting the better of you. Heck it happened to me and in trying to add more features, I broke my game and couldn't fix it in time to submit.
A hard lesson I'll keep in mind for the next game.
