TouchArcade Rating: A masterful blend of distinct gameplay styles is what makes Ocean Keeper shine. It seamlessly integrates side-scrolling mining with top-down mech combat, creating a compelling and replayable experience reminiscent of titles like Blaster Master and Dave the Diver.
In Ocean Keeper, players crash-land on an alien underwater planet in a powerful mech. The core gameplay loop involves descending into underwater caves to mine resources within a time limit, as waves of enemies approach the surface. The side-scrolling mining segments focus on excavating resources and artifacts, earning in-game currency. Once the mining window closes, the action shifts to a top-down twin-stick shooter, where players defend their mech against increasingly challenging waves of aquatic creatures, incorporating light tower defense elements.
Resources gathered during mining are used to upgrade both the mining equipment and the mech, with extensive branching skill trees for customization. The roguelike nature means death results in the loss of run-specific progress, but persistent upgrades between runs ensure continuous advancement. Randomized overworld and cave layouts add to the replayability.
While the initial stages may feel slow, and early runs challenging, perseverance is rewarded. As upgrades accumulate and skills improve, Ocean Keeper unfolds into a fast-paced, deeply satisfying experience. The strategic depth lies in experimenting with various weapon and upgrade combinations, leading to diverse and effective playstyles. The initial slow pace shouldn't deter players; the synergistic upgrades and engaging combat make for an incredibly addictive gameplay loop. Ocean Keeper's initial slow burn quickly transforms into an irresistible gaming experience.
