Click green flag, then you have 30 seconds to grab as many stones as you can. Move the ants out of the way and then click or press space as fast as you can over the stones to collect them. You get a bonus 10 seconds for collecting the big stone, and if you make a perfect 100 then as a bonus 50 more stones come into play :)
Stone Behaviour: Stones have a panic level - When panicking, they move faster and won't settle under an ant until calmer. When not panicking, they will select the nearest ant (if not too far away) and turn towards it as they walk + a little randomly wiggle. When they are safely under an ant they stop moving and settle down (They also point themselves in a random direction at this point so that if they are disturbed they will all scatter away). When a stone is at rest and is disturbed, then it begins to panic and therefore runs off. There is one more behaviour that is taken when at rest. Randomly (1 in 1000 chance), a stone will decide it want to go for a wander and changes ant. This is done by having a variable that says rest under any ant except 'this' one.
