This is a minimalist free-kick football game in which you truly control how you kick the ball by selecting:
The power of the kick
The contact point on the ball
The direction of impact
Those parameters decides the trajectory, and the animations are just scenery.
When the contact point is off-center, the ball spins and is affected by the Magnus force.
If the ball spins horizontally, its trajectory curves left or right.
If the ball spins vertically, the Magnus force pushes it downward, causing the ball to dip faster (see "David Luiz's freekick masterclass" on Youtube)
