Thanks for a kind words. The original plot is described as:
A giant mutated television set known as the "Fuzzbomb" has begun infecting cities across America and turning people into walking balls of TV static. The player controls a secret agent assigned to defeat the Fuzzbomb and rescue fuzzed people.
So as the Agent you must travel by trains across the country, give healing crystals to the people, rescue infected cities, and finally find the TV ("Fuzzbomb") and destroy it. The educational part is related to the geography, reading and typing (buying tickets is possible by typing destination names) - a good practice for 7-8yrs kids.
Personally I like the concept of spreading of the plague - as a player you feel how fast the time is running out. Also I feel the story has noticeable correlation with controlling masses via tv and social media. So the player's goal is to stop the plague, and mine is to draw attention to its presence.
