The rotation was "supposed" to make the ball harder to hit accurately (hence the time stop for aiming) but something went wrong with the physics so it doesn't work how it's supposed to but its nice to see people still enjoy it
Ah. I see!
Well, on one occasion the rotation mattered while i played: the ball got stuck behind a goal, and to get it unstuck precise timing with the rotation was required. NPC got in there first and recovered the ball. At the time i thought i just was to fat, but looks like the collision did at least something...
