I think it'd be a cool idea if you could pay (I don't care if it's even as much as like, a lighthouse) to remove ROCKS. My towns map layout is fabulous but I have 9 rocks. 9. All in the most inconvenient of places!
Oh my god, I didn't even know having over 3-4 rocks was possible!
But to answer your question, I wish there was a more...solid food source, maybe? Harvest Day just seems a little silly to me considering the only foods are fish and fruits...neither of which I'm able to eat.
wow, now that I think about it, we should be able to grow vegetables!
