Subby Quest

Welcome to a world swallowed by darkness. An underwater cave stretches endlessly before you, full of mystery, danger, and things you never expected to find. Explore it, survive it, and uncover what lies beneath.
Coins are scattered all across the deep. Grab them and spend them wisely, whether that's growing your submarine fleet or loading up on boosts to push through the toughest moments the cave throws at you.
And keep your eyes open. Rare gems are hiding in places most players never reach. Finding them is the real challenge.
The cave doesn't care how far you've come. It just keeps going. Will you?
