Made within the GGJ 2018 theme “Transmission”, it is about infecting people while players take control of the flu, trying to spread all across the human race.
It was inspired by elements of the flash game Toss the Turtle and 2D Top-view shooters. The game plays in two phases: Launch, where players must fling the virus to other people, and combat, where they must attack the hosts immune system in order to infect him.
On the launch phase, when the virus touches an organism a transition to the combat phase was implemented inspired on Final Fantasy VII combat transition.
A shader was written, consisting in blending past shown frames by an alpha value and rendering to the screen the result.
