It doesn't seem like the images are retina/hd ready. I don't mean to sound spoiled, but when a site doesn't have retina/hd compatible vector graphics, they immediately lose a lot of credibility to me (most sites that I run across that don't have retina/hd graphics haven't been updated in years, so that's most likely why). There are a lot of tools and plugins that can help with the exporting and displaying of retina/hd graphics. It's not the end of the world if a site doesn't have them, but it's immediately noticeable.

Paddle itself looks awesome though :)
