PROPAGATE is a game in which you need to move a ball across the field without touching any objects. Small purple zones will appear on the field, which will narrow over time. You need to stay as long as possible and as close to these circles as possible, since points are awarded for this every second. But you also need to not stand near them for too long, because after narrowing, a red expanding area will appear that can kill you. If you touch any red object, the game is over.
