Abysswward

A one-thumb deep-trench arcade game. Hold to gather your bioluminescent light, release to cast a shockwave ward that shatters the swarm closing in from the dark — and chain multi-kills for escalating score. One press-and-hold, endless escalating intensity, SURGE waves, and a razor-thin risk/reward: charge longer for a bigger blast, or fire early before they reach your core.
