How to Play

1. The elephant appears on screen — memorise where the eye is
2. The elephant hides
3. Move your cursor (or finger via camera) to where you think the eye was
4. Drop it — and see how close you were!

Two input modes are supported:

Mode	How to start	How to drop
🖱️ Mouse	Press M or click [M] Mouse	Click or press Space
📷 Camera	Press C or click [C] Camera	Pinch your index finger and thumb

Your best score goes on the leaderboard. Higher score = closer to the eye, faster.
