Two horizontal sliders (not vertical) control crown positions in a text/ASCII canvas, with correct physics values and live stats, but slider direction is inverted (0=crown high, 100=submerged maps left-to-right not top-to-bottom), there is no fall animation, and the ASCII art crown positioning logic is numerically shallow (crowns barely move on screen due to the 0.15 multiplier).
