CORESHIELD — One-Thumb Arcade

CORESHIELD is a sharp one-thumb arcade core-defense game. You are a neon core at the center of a dark void — tap to emit an expanding shockwave that shatters inbound shards before they breach your heart. Chain combos for multipliers, land precision kills near the shockwave's rim for 2× points, charge OVERDRIVE for a screen-clearing blast, and survive waves that escalate every few seconds. 4 enemy archetypes (splitters, phantoms, shielders, warpers), juicy screen shake and hit-stop, persistent local high score. One finger, instant restarts, pure arcade loop.
