Mike-
Thanks for putting this together, it looks great.
I made a few edits to the beginning (which we can discuss), but I think the bulk of it looks good. I uploaded the version with my edits to Google Drive.
Again, we can discuss it in person, but my biggest concern is that adequately discuss both the walk-through from the user's perspective, and the technical topics behind it. I think the script does a great job of walking through the user's experience with the app, but that we could spend more time describing the design behind it. For example, in the script, we have a description of how the login system works (and all the levels), but it doesn't really explain the technical details behind what is happening (e.g. that we're making a call to the cloud, etc.).
I think we should discuss the script in person to finalize it (we also need to make sure it reflects the final version of the app), but I think it's generally good.
