Letter Flow Drag Interaction

This interaction showcases a playful word puzzle game where players drag letters horizontally to rearrange them. The letter container uses a fluid, organic metaball/liquid morphing effect that stretches and merges as letters are dragged and swapped. The background features a soft, dynamic gradient that shifts color in response to user actions. Upon successfully spelling the target word ('GREEN'), the background transitions to a vibrant green, the letters snap into a clean alignment, and a colorful confetti particle explosion celebrates the completion.
