Thanks, added update to reduce the size of the target zone, so the ants on the back wall will be less likely to go "in". Defined an active zone for placing ants, if double-click is outside the zone, the ant will be placed at the boundary. I opted for the "dead fall" as a design alternative to an elastic collision in order to limit the number of bounces off the back wall when too much speed is applied by the player.
