This game shows off three issues:

- Met with an impassable slope, Spring pathing causes extremely rapid sliding along the edge of the impassable area. This sliding violates the max velocity constraint. Here chickens jitter left-right to a distance of about half a cloaky factory, passing that distance in two directions many times per second.

- This sliding can also lead to units stacking denser than what would be physically possible for solid objects. This violates both footprint and unit-unit collision sphere constraints. Here, approximately 20 chickens stack and merge into a space smaller than one Stardust.

- While doing this, the 20 chickens also fail to perform the thing where tightly packed chickens throw some of their kind over the obstacle - no chickens are launched despite extremely tight packing. I guess something broke the mechanism.

Ah. I thought that was a good feature.
