There do appear to be a couple videos, but they are linked on the Bio page. Kind of hard to find. Also, I cant really get a grasp of the steps you took to design good gameplay from the screenshots or the videos.

Show/tell(briefly and concisely) design decisions revolving around gameplay.
As was already said, a bit of scripting never hurt.
