juegazo bastante entretenido, excelentes mecanicas, hermosos graficos, muy optimizado y sobre todo calidad-precio
Fun game with friends. Many enemies, trophies and things to add as collections. Requires much exploration, better with friends if you want to find everything. Fun times for many hours.
Jogão.

10/10 - Core Keeper: A Gentle Light Beneath the Stone There are games that entertain you, and then there are games that quietly wrap themselves around your heart like a warm blanket after a long day. Core Keeper is the latter — a cozy, intimate adventure that feels less like playing and more like returning home to a world that has been patiently waiting for you. You begin alone in the flickering dark of an ancient underground cavern, lantern in hand, the weight of the earth pressing softly overhead. The air is cool and still, broken only by the distant drip of water and the gentle hum of glowing crystals. What starts as simple survival — mining stone, tending crops in bioluminescent soil, crafting basic tools — slowly blossoms into something far deeper. With every swing of your pickaxe, you’re not just gathering resources; you’re uncovering stories. Forgotten relics, mysterious journals, and the quiet ruins of civilizations long past whisper of wonder and resilience. The underground world of Core Keeper feels alive in the most comforting way. Vast, interconnected caverns filled with glowing flora, shimmering lakes, and creatures that range from curious to protective. There’s a peaceful rhythm to the days: planting seeds in your growing base, exploring hand-in-hand with friends (or alone with your thoughts), cooking hearty meals over a crackling fire, and retreating to a cozy bed as the world above remains forever out of reach. The lighting is masterful — soft blues and warm oranges dancing across stone walls, creating spaces that feel both vast and intimately yours. What makes this game truly special is how it nurtures connection. Whether you’re playing solo or with loved ones, the act of building a shared base, defending it together during carefully telegraphed events, or simply sitting by the water sharing stories turns the underground into a sanctuary. The bosses are challenging but never cruel; overcoming them feels like a shared triumph rather than a test of reflexes. Progression is satisfying without being punishing — every new biome you uncover feels like turning the page of a beloved storybook. There’s a profound coziness in the details: the way your character’s footsteps echo softly, the satisfying clink of crafted items, the gentle music that swells at just the right moments. It’s a game that respects your time while inviting you to lose yourself for hours. In a noisy world, Core Keeper offers quiet purpose — the joy of cultivation, exploration, and creating something beautiful in the dark. If you’re seeking an adventure that feels personal and warm, one that rewards patience and curiosity with wonder and a sense of belonging, then light your lantern and descend. The underground world of Core Keeper is waiting with open arms and glowing hearts. A true hidden gem that continues to shine brightly. Highly recommended for anyone who needs a gentle, immersive escape. 🌿🪨✨
