Hey, I'm glad to hear that you're enjoying it!
11 hours is just the rough average of how long people tell me it takes them to finish the whole thing (not just the update) - though there is a lot of variation, with some people being almost twice as fast, and others being slower. Between then ends of 0.3 and 0.6 there should have been an extra 4 (long) days added, with the final day in the current version being day 18.
