Good job. I really like the idea of a narrator describing the story, like in Bastion. There's a lot of scope to do interesting things. Some extra dialog and story elements would be a nice addition in a future version.
I had an issue playing in Chrome on Mac. The arrow keys scroll the html page as well as moving the character - the WASD keys did not respond for me. This might be fixable without changing the game by just enabling the option to allow players to run the game in full-screen mode.
