Plunge into Tidehold, the indie strategy sensation that lets you command an underwater colony clinging to survival beneath the waves! Crafted in just 72 hours for Ludum Dare #57, this free browser game delivers a unique blend of resource management, base expansion, and mysterious adventure. As your colony’s leader, every decision matters—grow your population, balance oxygen production, and venture into darkness in pursuit of a mysterious signal that could hold the key to your future.

Tidehold’s gameplay is tense and rewarding, driving you to juggle the construction of farms, houses, and mines to keep citizens productive and fed. Expanding your colony isn’t just about numbers—it’s about managing the precious O2 that keeps everyone alive.

But this isn’t just survival—the ocean is full of secrets and lurking dangers! As your reach extends deeper, use radars to navigate the abyss and detect threats before they strike. The haunting soundtrack and atmospheric pixel art create a truly immersive underwater world, where glowing lights pierce the endless blue and every expansion feels like a leap into the unknown.

Playable on desktop and mobile, Tidehold brings city-building and real-time strategy together in quick, satisfying sessions. Players will love the feeling of tension as they push the boundaries of their underwater territory and uncover the truth behind the enigmatic signal. Will your colony thrive, or will you be swept away by the dark currents below?
