PULSECRYPT
PULSECRYPT is a crimson-neon one-thumb arcade game. You are a pulsing core at the center of deep space — tap to emit a shockwave that destroys incoming shards. The closer enemies get before you blast them, the higher the score multiplier (4x proximity bonus). Each pulse leaves behind a lingering Echo Ring that damages enemies who cross it. Chain combos for a x25 multiplier, build Overdrive for a screen-clearing blast, and survive escalating waves of 4 enemy types: Splitters, Phantoms, Shielders, and Warpers. One thumb, razor-sharp risk/reward.
