Gozpadi is a reflex-testing game where you trace moving shapes to match stationary targets. Every millisecond counts as you race against the clock, pushing your precision and reaction time to the limit. Designed for players who want to sharpen their reflexes, compete globally, and master the art of accuracy under pressure.

How to Play
A shape darts across the screen. A stationary target outline sits in the center. Tap the screen exactly when the moving shape aligns with the target. The closer the alignment at the moment of your tap, the higher your accuracy.

How Accuracy is Measured
At the moment you tap, the system captures the exact position of the moving shape. It then calculates how closely the shape's outline overlaps the target outline. Overlap is measured using geometric distance between thousands of sampled points on both shapes. Perfect alignment = 100%. Even a slight miss will lower the percentage proportionally. You must reach the level's required accuracy threshold to advance.

The Hausdorff distance is a way to check how similar two shapes are by looking at their edges. It was created by a mathematician named Felix Hausdorff. Imagine you draw two shapes on paper.

To compare them:
1. Pick a point on the edge of the first shape.
2. Find the closest point on the edge of the second shape.
3. Measure the distance between them.
4. Do this for all points on the shape.
The Hausdorff distance is the biggest distance you find.

It tells you the worst mistake between two shapes. If the shapes match perfectly, the distance is 0. If one part sticks out or is far away, the distance becomes big.
