## Description

Pin Ring is a vertical ocean survival evasion mobile game that combines rhythm control with precise movement. Players control an energy core traveling through deep-sea channels, tapping the upper half of the screen to rise and the lower half to dive, skillfully avoiding ice crystals and coral reefs surging from the right while finding paths through narrow gaps. As the score increases, obstacle spawn rates rise, channel gaps narrow, and movement speed steadily climbs, making each wave more intense. The game supports pause and quick restart, and automatically records the highest score. Simple rules make it easy to pick up, yet high-speed gameplay tests reaction and rhythm, offering both casual fun and strategic depth.
