Since you liked Plague Inc why not try Bio Inc.
Its a similar concept as plague inc but instead of focusing on the whole world it focuses on a singular person and their various systems. You are essentially trying to kill the person.
Bio Inc on google play, a game I believe is what you mean. https://play.google.com/store/apps/details?id=air.com.dryginstudios.bioinc&hl=en
