Thx! This is what I needed :).
Actually there is an infection mechanic that is seems to be really poorly conveyed to the player: Any facebeing can be infected and it is undetectable on the first stages, and shows as color-changing coughing on late stages. At last victim begins to cough out his eyes. It can be cured by golden apples. At the beginning some people in "town" are infected and you theoretically could try to cure them before chaos breaks loose.
Ah, I see. And the cluster of connected nodes is the virus?
No offense but I thought it was an acid trip game especially when I lost my eyes and saw it floating around somewhere and the strange dialogue (which I honestly liked to some extent). Looking back now, it makes a whole lot more sense ^ _ ^.
