statistical minima are the corners. if you wait there, you can see that red particles almost never come for first levels. for next levels, you have to observe red particles well, and if one of them "really" comes, you can use a cat or hyperspac... i mean you can jump from a corner to another with using out-gamescreen mouse movements. enough physics for 200 seconds.
