Sub Abyss

Your submarine surges forward through the abyss. Hold to rise on bubbles, release to sink, and weave past wrecks and jellyfish tendrils. Scoop sonar buoys for points and thread narrow canyons for big bonuses—one hit ends the dive. Watch oxygen and pressure gauges; lingering too deep or running dry becomes deadly. Currents, swarms, and scarce air kits escalate the tension of every meter. Readable one-thumb controls with a cold, glowing deep-sea mood for players who love survival distance runs under the waves.
