Great job on all of these films, the interactivity was appreciated as well. I think the cockroach one was probably the funniest, though my favourite overall was probably the piggy bank segment, it managed a good mix between being funny, and genuinely quite poignant. The fish film was probably my least favourite out of the three, though it was still very good. While the ending was definitely tear jerking as well as darkly humorous, I just didn't think it was overall quite as amusing or entertaining as the other two.
I also love the little surprise after you watch all the films, and wouldn't mind seeing a finished version of it some day.
