You’ll miss the Flash and .gif animations, but Hussie notes the URLs of each page ON EACH PAGE. So you can’t miss ‘em for long. Especially if you miss the music. [:
Also, if you’re thinking about getting the books but you don’t think you’ll enjoy them without those things previously mentioned, put that thought away. Our beloved (or behated, I guess, depends on the update right? Hahaha) Andrew Hussie has left author commentary on every page, giving insight into how he drew the panels or how the story was being shaped at that particular point in the story.
