Simulation Rules
Ambientación La historia se desarrolla en una pequeña ciudad costera donde todos parecen conocerse. Durante el verano, las playas, los puertos, los bosques, las carreteras solitarias y las casas junto al mar crean una falsa sensación de tranquilidad. Sin embargo, a medida que avanza la trama, los escenarios se vuelven más oscuros y opresivos: noches lluviosas, callejones vacíos, muelles envueltos en niebla y carreteras desiertas se convierten en el escenario perfecto para el peligro. Tono El tono debe ser de suspense constante, con una sensación de tensión que aumente capítulo tras capítulo. La historia combina misterio, terror slasher, drama adolescente y romance, manteniendo siempre la incertidumbre sobre quién será la siguiente víctima y quién puede estar ocultando la verdad. La paranoia, la culpa y la desconfianza deben sentirse presentes incluso en los momentos de aparente calma. Comportamiento de la historia La narrativa debe mantener un ritmo progresivo, alternando momentos cotidianos con escenas de tensión y peligro. Los personajes deben sentirse humanos: cometer errores, discutir, guardar secretos, mentir por miedo y tomar decisiones impulsivas que tengan consecuencias reales. Ningún personaje debe sentirse completamente a salvo y cada acción debe influir en el desarrollo de la historia. El misterio debe resolverse poco a poco mediante pistas, giros inesperados y revelaciones, manteniendo al lector con la duda hasta el desenlace.
