Two independent sliders (not one unified control) move both crowns but the direction is inverted (slider max=100 pushes crown up in the ASCII grid rather than down into water), splash effects are stubbed but never rendered, and the ASCII art water visualization is rudimentary with no real per-cell fill logic.
