After looking over the feedback you gave me Phil, I have had a rethink of ideas in terms of how to approach this project.
Initially my Influenza virus world took place inside the body with a invasion principal. I am keeping the invasion principal and transferring it out of the body and into a ''kid-friendly'' world. I want to make a demo/teaser of a game where the viewer is asked to select a character from a wheel of silhouettes, from this they choose the virus, the silhouette takes on its full shape and a little bit about the character is told at it's side. When they confirm their selection the screen fades and re enters with a cinematic pan of a village which contains the cell's going about their daily lives in peaceful way. Again the screen fades and re enters with a hill where the sun is shinning, the sun is then being ''invaded'' by an eclipse caused by zeppelin like ships which appear of the hill and encase the village in darkness. Screen fades again, re entering inside the zeppelin where thousands of the virus characters are waiting to be deployed. The bay doors open and the viewer is shown to have taken control of the virus and instructed to attack civilians, in doing so they have to press buttons corresponding to the way an infection attacks a cell. They succeed in infecting the cell and a message pops up telling them so. But the screen flashes red in warning and the viewers see the castle/fort where little white soldiers with shields and spray sticks run out and begin spraying the infectious cells. The screen pauses on one of theses characters as it approaches the viewer and it gives a little detail to say that they are the antibodies. At least that's the idea anyway. I am going to start with a script to get it out and structured and upload the thumbnails I have presently.
Bellow are some influence maps I put together after researching the idea around soft artwork within games. Something that would be appealing to young children, specifically to my ages group (9-11). Children now love to play games and I think it's important not to scare them too much, but at them same time make them feel interested into the concept of the game.
