I just finished the demo. Not a bad start!
A couple of things:
1) Some parts need to be translated. I think the greeting with Ash and some of the menu options are the most obvious examples.
2) You want "whatever", not "wharever". "Whatever" is what someone says when they don't really care.
3) My personal recommendation is to start small and then add on to it. E.g. maybe make complete routes for Ash, Rie, and Cris and then work on stuff for Bianca and Jake afterwards. This way even if you stop development, you still have a good finished product!
4) I enjoyed the demo! I hope you'll continue working on it!
