Umigame: Fight Your Way Out of the Haunted Swamp

Umigame is a stylish and innovative action roguelite developed by the small, dedicated team at Nimblegames. Released into Early Access on Steam, this title successfully merges fast-paced, fluid combat—inspired by games like Hades—with strategic tower defense mechanics. You play as a water spirit fighting through a beautiful yet corrupted world known as the Haunted Swamp.

Game Story and Focus: Corruption and Spirit Evolution

The game's setting centers around the Haunted Swamp, where the malevolent influence of Witch Maeve has corrupted the environment and turned native creatures into cursed abominations.

The Narrative: You embody a water spirit (Umi) summoned to the swamp. Your main goal is to grow stronger with every run to defeat the terrifying bosses and break free from Maeve's chaotic influence.
The Focus: The primary focus is endless replayability through randomized environments, skill synergy, and permanent progression that makes every death a meaningful step toward mastering the swamp.

Key Features Defining the Roguelite Experience

Action Roguelite Core Combat: Engage in smooth, swift, and satisfying hack-and-slash or ranged combat. Utilize a dash and refined hitboxes to survive relentless enemy hordes and thrilling boss battles.
Guardian Turret System (Tower Defense Blend): A defining mechanical blend. You can summon and command Guardians—natural turrets—to fight alongside you. Deploying and modifying these units adds a crucial layer of tactical decision-making to the combat flow.
Unique Playable Heroes: Start with core characters like Lyra (archer) and Olaf (melee fighter). Each hero possesses unique weapons, abilities, and playstyles, encouraging experimentation with different combat builds.
Deep Progression and Builds: Stack absurd character builds using over 150 unlockable skills and items. Permanent progression is tied to Soulshards, which are collected on each run and spent in the Sanctuary to permanently upgrade your heroes and Guardians.
Online Co-op: The game features dedicated online co-op for 1-2 players (with plans to expand to 3), allowing friends to combine powers and strategies to tackle the escalating difficulty of the swamp together.
Difficulty System: Once you complete the game in its current Early Access state, an Unlockable Difficulty System ensures ongoing challenges and fresh content through customizable run modifiers.
