So I had the idea that when the virus is attacking Mia internally, it would be like Space Invaders, that simple classic game style, with both organic and digital elements as the aliens and Mia's face shooting lasers out of her mouth at them.

However, upon completion of the visual for this, I think Pac-Man would be much better...

I think this Pac-Man style works a lot better, although I have removed the use of computer components attacking Mia's head, I have her chased down by the biological viruses running on a loop. I have also edited the pac-Man game screen, adding circuit boards to give it a digital, inside a computer feel, representing the inside of Mia's brain.
