Hmm
This is a good flash but not as good as the past ones, seems they got TOO ambitious with the project, that is, really complex scenes with many characters to animate but instead animated it partially. There were many really choppy parts and too many still frames, there used to be a lot of more animation at past episodes. Don't know, maybe you ran into a deadline or something but... well... I found it lacking, hope episode 5 concludes great with great plot and animation.
BTW, I felt the horizontal pan was kind of jumpy...
