Its a really nice base for an iddle game! Its a pitty it does not work on Firefox, but I just played it on Chrome and it works fine untill day 11.
It would add a very nice touch to have some animation of the villagers, maybe in the footer of the page or something like that.
As for the gameplay, I do reccomend to make "needs" visible when you click on them (or to have them displayed all the time), not only when you hover your mouse over.
I liked the music and the nice touch of increasing the speed to match the moon speed level!
