Ruptura

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a two-player, turn-based, deterministic abstract board game titled “Ruptura,” presented in Spanish. Use a dark, polished UI: near-black/navy radial-gradient background, centered responsive app, gold uppercase title “RUPTURA,” and a square 8×8 canvas board inside a dark rounded panel with a thin gray border and shadow. Add a right-side panel on desktop (stacked below the board on narrow screens) showing the current turn, Spanish rules, a scrolling move log, and a gold “Reiniciar partida” button; footer text should show the current hint and “R = reiniciar”. The header labels should indicate “juego de tablero asimétrico” and “2 jugadores · sin azar”.

The board is an 8×8 checkerboard filling a square canvas. Alternate tiles are muted tan (#c7b98e) and dark blue-gray (#303747); subtly tint the entire top row gold. Start with these exact pieces and coordinates, where x=0 is the left column and y=0 is the top row: Sol (gold/cream) has a Núcleo/core at (3,7), Guardianes/guards at (2,7) and (4,7), and Corredores/runners at (1,7) and (6,7). Sombra (red) has a Guardián de Sombra/warden at (3,0) and Acechadores/stalkers at (1,0), (2,0), (4,0), (5,0), and (6,0). Render each piece with a soft dark drop shadow and outlined luminous styling: Sun pieces are pale gold with light cream borders and dark brown symbols; Shadow pieces are coral-red with pale red borders and dark maroon symbols. Render the Núcleo as a gold circular token containing a diamond glyph, the Guardián de Sombra as a red diamond/shield-like polygon, Guardians as circular tokens marked “G,” Runners as circular tokens marked “R,” and Stalkers as circular tokens marked “A.”

Sol moves first. On a turn, the player clicks/taps one of their own pieces, then clicks/taps an illuminated legal destination. Highlight the selected square with translucent blue, show legal non-capture destinations as small translucent blue circles, and legal captures as larger translucent red circles. Clicking another own piece changes selection; clicking elsewhere cancels selection. Disable interaction after game over. Support mouse, touch/pointer input, a reset button, and the R key.

Implement these exact movement rules: the Núcleo moves one square in any of the eight adjacent directions. A Guardián moves one square orthogonally. A Corredor moves one square diagonally in any diagonal direction. Each Acechador moves one square diagonally downward toward increasing y only (to x−1,y+1 or x+1,y+1). The Guardián de Sombra moves one square in any of the eight adjacent directions. A move may target an empty square or an opposing piece, provided it is on the board; friendly-occupied destinations are illegal. Sun pieces may not capture the Núcleo; the Shadow side may capture it. (The movement implementation should otherwise allow opposing-piece captures.) After a valid move, update the piece coordinate, log the move in Spanish, log captures, and alternate the turn.

The win conditions are exact: if the Núcleo reaches y=0, finish with “¡El Sol rompe la línea y gana!”; if any Shadow piece captures the Núcleo, finish with “¡Sombra captura el Núcleo!”. On game over, clear selection, show “Partida terminada” and “Reinicia para volver a jugar.” in the turn panel, put the result in the hint area, and stop further moves. At game start log “La partida comienza. El Sol debe romper la línea.” and show “Sol empieza.” The move log should prepend entries, retaining only the newest eight entries. Use responsive layout behavior: desktop has board and approximately 260px sidebar side by side; mobile stacks them, hides the rules, and uses a compact two-column sidebar. Keep the aesthetic minimalist, flat-shaded, high-contrast, and board-game-like, with no animation or randomness required.
