I decided to give your demo a quick try.
I didn't get very far (I had just left the city).
I saw quite a few grammar mistakes, so you should probably proof read some of your stuff. If this has been mentioned before, sorry. :/
You abused the hue changer on some of the NPCs, and to be frank - it doesn't look all that good. You should probably just make them new sprites.
I also noticed that there was no music in any of the buildings, which is just something that bugs me. O.oa
I also think there should be some battle animations, to make it more interesting. XD
I'm glad that you did not start your game off with white text on a black screen, and have your hero wake up. I've seen that too often. ^_^;;
Good luck with your game! :3
