I thought this wasn't as good, probably because it actually had TOO much plot. It inverted the problems of the previous entries. There was just too much dialogue. I would like it if you had some actual audio with the dialogue. It's still pretty creative. I also still like the music.
It just isn't that rewarding. Then again, it is just a silly series. I can tolerate that. You seem to use some different animation styles here. That could just be the different pictures used, however.
