People are saying that, but I'm skeptical. Language is pretty versatile. If Wikipedia can explain the concept of an ergosphere to me without video, surely it can be done for somebody's iPad game.
That's kind of funny. "It's not understandable without the video" can be complete agreement or complete disagreement with what I'm saying depending on what "it" is. Stupid language.
I believe the product is, platonically, understandable without a video.
PS: I like misusing the word platonically
