Ah real pity you took on too much and couldn't get there. You really have to go for a solid small feature set and have 'stretch goals' for other things you'd like in a game jam. It's called the MVP, minimum viable product ... what's the absolute minimum featureset you can have and be happy enough.
Of the games i've played so far though it's one of the most unique concepts, no one really did a 'go regenerate the world' kind of theme.
