This is my top game of the Vancouver GGJ 2011. Most innovative idea that I saw at the jam, even if the difficulty needs a lot of love. In the interest of other people checking this game out, here's a rule summary:

1. There are 3 disease carriers in the general population. They look just like normal people, but they don't noticeably suffer from symptoms.
2. When a normal person touches one of the carriers, they slowly become green and die. These people are NOT contagious.
3. You have limited bullets to kill the 3 carriers. You can also toggle the grenade with F
4. You win by carefully observing the crowd to see who could be the carrier. You can't notice the carriers themselves, but you see their effects - the green, sick people.
5. Kill all 3 within the time limit to win
