Ratatan is a rhythm roguelike action game that blends precise beat-matching commands with side-scrolling battles and roguelite progression. Players take control of one of several Ratatan characters who lead squads of Cobun through runs across multiple worlds, issuing timed inputs to direct attacks, movement, and defenses against waves of enemies.
Gameplay
The core loop centers on rhythm sequences that players input in time with the soundtrack to command their Cobun army. Basic commands handle marching, attacking, guarding, and jumping, while special abilities and ultimate attacks build from consistent timing and Fever mode triggers. Each run involves navigating side-scrolling stages filled with melee encounters involving dozens of units on screen at once.
Progression mixes run-specific upgrades with persistent systems in the Rataport hub. Players collect materials to enhance Ratatan characters, Cobun units, and weapons through dedicated facilities. These upgrades influence attack types, elemental effects, critical hit potential, and defensive options across repeated attempts. Eight distinct Ratatan options provide varied tactical roles, from area control and protection to ranged damage and status effects, each paired with unique Cobun weapon sets and Fever abilities.
Visuals emphasize lively 2D animation during combat, with the soundtrack driving the flow of battles. Positioning the Ratatan leader and timing retreats add strategic layers beyond pure rhythm execution.
Game Modes
Single-player runs form the main experience, guiding Cobun squads through sequential worlds and episodes toward story objectives. Roguelite elements allow adaptation through room rewards and build choices between encounters, with meta-progression carrying over across attempts.
Online co-op supports up to four players in shared sessions, where combined Fever activations amplify group performance against large enemy groups. Progress from co-op carries into individual saves, though cross-platform save sharing is not available. The full release includes completed story episodes with multiple bosses and a final encounter.
Story and Setting
The narrative follows Ratatan inhabitants of Rataport island as they journey toward The Everafter in search of the Goddess. Failures reset runs but encourage persistence through the roguelite structure. Hub areas like Rataport feature support facilities where collected materials improve character and unit capabilities for future expeditions.
Worlds introduce varied environments and enemy types, building toward larger confrontations. Recent updates expanded episode content and added new boss encounters tied to the ongoing story.
Is It Worth Playing?
Ratatan appeals to players who enjoy rhythm timing combined with tactical army command and roguelite variety. The game launched in full form in October 2026 with completed story content and regular patches that refine balance and add features. Reception highlights the charming presentation, addictive command flow, and strong soundtrack, though some note the rhythm inputs can feel repetitive over long sessions and the difficulty curve demands practice.
Those drawn to spiritual successors of rhythm strategy titles or short co-op sessions with friends will find a solid match in its systems. Single-player remains fully viable without multiplayer. The upgrade material sets available as add-ons directly support the core crafting and support facilities in Rataport, providing immediate boosts to progression for new or returning players focused on optimization.
