Good work so far. Some things to work on would be the way NPC's text is presented. Error messages aren't the best way to tell your story, especially if the volume is all the way up and I'm inches away from my speakers, not expecting the explosive report of this sort of message box. You'll want to, of course, have the character's walk animation stop when he isn't walking, but I'm sure you know that. The animation looks good from every direction while walking. The text box shown when the game is paused looks like it would be good for displaying NPC speech, and I imagine that's what you plan to do.
Keep it up!
EDIT: Does not run in release mode. This could be a problem later on, and you'll want to sort out what's causing this before you get too much further into the project.
