Pretty fun to play and a very impressive demo, although I will admit I'm not a huge fan of Harvest Moon games. The inventory system is good, and I appreciate the little touches like being able to immediately go outside from your room or any point in the inn. Also the corresponding folding/unfolding wall animations.
I think your world needs more color though, I don't like the gray-white of the inn and the rocks. The grass and water are what the rest of the world should look like.
It's also fun to feed customers spiders and rats
