Nice site, well done!, maybe the navigation is not entirely clear
..with Hype you can make decent site? yes. Some things are missing but with few lines of codes you can fix the issue.
Page name in the URL for each scene, back to top ( on load the new scene), slideshow through prettyphoto and so on.
The workflow is a bit slow but the result is nice. Also with only 3 layout per scene you can get a good result.
I think this new feature ( mediaquery) has yet to be fully understood.
So, in my opinion Hype is made also for the web design.
