TouchArcade Rating: A masterful blend of distinct gameplay styles is what makes Ocean Keeper shine. It successfully integrates side-scrolling mining with top-down mech combat, creating a compelling and consistently engaging experience. Think Blaster Master's vehicle/on-foot action, or the restaurant management and roguelike diving of Dave the Diver – Ocean Keeper shares that same satisfying duality.
The core gameplay revolves around your crashed mech on an alien underwater planet. You'll explore underwater caves, mining resources and artifacts in side-scrolling sections. This mining phase is timed; you must return to your mech before waves of enemies attack. The combat shifts to a top-down twin-stick shooter with light tower defense elements, challenging you to repel diverse underwater creatures. Mining yields coins used for upgrades.
Resources fuel upgrades for both your miner and mech, with extensive branching skill trees for customization. The roguelike nature means death resets your run's progress, but persistent unlocks between runs ensure continuous advancement. Procedurally generated overworld and cave layouts add replayability.
While the initial stages might feel slow, with challenging early runs, perseverance is rewarded. As upgrades accumulate and skills improve, Ocean Keeper truly blossoms. Experimenting with weapon and upgrade synergies becomes incredibly rewarding, offering diverse build options and tactical approaches. Despite a slow start, the game's addictive loop and satisfying progression quickly make it hard to put down.
