Hi Dreamavoider. Thank you. I am glad you enjoyed the special. It took me a week to write and a week to make all the images and animations. Although, I also spent a few evenings and a Sunday morning or two picking out the costumes and doing some of the storyboarding and generally coming up with all the ideas. So it's difficult to say exactly how much time I spent on it. I was also working flat out for the week I put all the images together and gave myself an RSI in my mouse hand, so such a pace of development isn't sustainable long term.
I switched to a new way of making animations last year and I'm gradually improving with the technique. The animations for the upcoming version 0.12 are leagues ahead of anything I used to be able to make. I think people are going to be quite impressed with the improvements.
