rhythm game style "in a futuristic metropolis, a luminous, iridescent submarine slowly ascends from the depths of the ocean, its undulating body releasing a symphony of gentle, shimmering notes that harmonize with the city's collective heartbeat. as it rises, the vessel transforms into a hovering sanctuary, emitting a soft, pulsating glow that soothes the anxious minds of those who dwell within. the once submerged hull now radiates an ethereal light that illuminates the clouds, its turbines replaced by delicate, crystalline filaments that generate a mesmerizing dance of glittering stardust and shimmering mist. as it pierces the sky, the sanctuary leaves behind a trail of gentle, luminescent sparks that guide lost souls to hidden oases amidst the city's ravaged streets. in the distance, a fleet of damaged drones slowly descends, their flickering led lights resonating with the hovercraft's soothing melody as they surrender to the sanctuary's calming presence. the scene is set against a backdrop of shattered skyscrapers, smoldering embers, and wispy smoke clouds drifting from the city's devastated core, where the whispers of ancient wisdom echo through the ruins." . music based gameplay, timing and coordination, soundtrack centric
