A realistic, tactile glass-fracture sound experience. Every reset pours a random water level into a newly tuned glass. Tap to grow branching cracks and hear the resonance change with water mass, then trigger a layered break made from crystalline shard tones, fracture noise, impact body, and a level-dependent splash. Includes responsive touch controls, procedural physics, local fracture history, keyboard support, and a focused headphone-friendly interface.
