PRISMCORE — One-Thumb Spectrum Arcade

PRISMCORE is a one-thumb spectrum arcade game. You are a prism core at the center of a dead spectrum — tap to emit refraction pulses that shatter incoming lightsplinters before they breach you. Chain proximity combos, ride the CHROMA risk meter (a fuller spectrum means a wider pulse, but overcharging triggers PRISM BREAK lockout), collect prism fragments for free pulses, and survive the escalating PRISM FLARE. Nova enemies split into two when destroyed; high score persists locally.
