Ratatan

Most action games hand you a sword. Ratatan hands you a drum and tells you to trust the crowd. The premise comes straight from Patapon, the PSP rhythm-strategy hybrid that turned button presses into marching orders, and Ratatan openly presents itself as a spiritual successor. It is developed by TVT Co. Ltd. and Ratata Arts and published by Game Source Entertainment. That lineage matters more than usual here, for reasons the reception makes clear.

The player never steers a hero directly. Instead, they lead a Ratatan commander and a swarm of small creatures called Cobuns by drumming command sequences in time with the soundtrack. Every order travels through the beat: advance, hold position, attack, retreat. Around that sits a roguelike structure. Each run pushes through hostile stages, and the upgrades and equipment collected along the way strengthen the army for the next attempt. Up to four players can join in online co-op, each bringing a commander and a squad of their own.

The release history is long. Ratatan entered Early Access on PC in September 2025 and launched its full version on October 14, 2026 on Steam and Nintendo Switch 2. That gives it an unusual market position. It is a roguelike, which is a crowded genre, but what sets it apart is the way players give orders, not the run structure. Few games ask players to command an army through rhythm, and Ratatan is betting that this alone will carry it.

Reception splits along a clear fault line. The concept earned enormous goodwill, and the finished product spent a large share of it. All-time user reviews on Steam sit at Very Positive, while reviews clustered around the 1.0 launch turn sharply mixed. That gap is the most telling signal about the game. The idea landed; the finished version did not.

• Rhythm-driven command system: Drummed sequences, played in time with the music, order troops to advance, take position, attack and pull back. Keeping the beat and reading the battlefield carry equal weight.
• Commander-and-crowd armies: A single Ratatan commander leads a mob of Cobuns. The player directs the group, never an individual hero.
• Large-scale side-scrolling battles: Fights can fill the screen with a crowd of characters at once.
• Roguelike runs with carry-over progression: Each push through hostile stages yields upgrades and equipment that strengthen the army for later attempts.
• Four-player online co-op: Every player gets their own Ratatan and Cobun squad, so co-op adds armies rather than splitting one.
• Hand-drawn 2D presentation: Animated 2D art and a catchy soundtrack frame a story about a community of creatures traveling toward a mysterious goddess.
• Broad 1.0 release: Available on Steam and Nintendo Switch 2 after a PC Early Access period that began in September 2025.

The Drum as Controller

Ratatan’s central design decision is indirect control, and it is a good one. Taking the hero out of the player’s hands moves the challenge from execution to timing and judgement. A command played on the beat is a correct input. A command played at the right moment in the fight is a correct decision. The game demands both at once. The music keeps going whether the battlefield has resolved or not, and that friction is where the tension comes from.

Orders are sequences rather than single presses, so every command costs time measured in beats. That turns tempo into a resource. Ordering an attack means committing a stretch of music to it, and calling a retreat means accepting that the troops will not react instantly. This works as a natural limit on button-mashing, and it gives the four basic orders (advance, hold, attack, withdraw) real tactical weight. A retreat called one bar late is a mistake the player made, which is the kind of failure a roguelike needs: easy to read, clearly the player’s own, and fixable on the next run.

The commander-and-crowd structure reinforces this. Directing a mob of Cobuns instead of a single character changes the fantasy from heroism to leadership. When a crowd of characters shares the screen, the player’s job is to set the pace of a battle, not to win individual duels. Most games in the genre test personal reflexes, so this gives Ratatan a distinct identity.

The Roguelike Layer

On paper, rhythm games and roguelikes belong together. Both run on repetition, and both reward players who learn patterns. A run-based format gives the drum commands time to become muscle memory, and carry-over upgrades and equipment give failed runs a purpose.

The trouble is how much of the army’s strength depends on that carry-over. When power comes mostly from gear accumulated across runs, the loop starts to measure time spent rather than skill shown. The recurring complaint from Steam players is the equipment grind and repetitive content that Early Access never resolved. The wider reception points to balance problems and systems that feel convoluted or excessive. These complaints describe the same structural flaw from two angles. Ratatan’s best idea is simple: play the beat, read the field. The progression systems pile layers on top of it until that idea has to compete for attention.

We think this is the game’s defining weakness. A rhythm game already asks players to replay the same songs, and a roguelike already asks them to replay the same stages. Add a heavy gear chase to both, and repetition stops helping players improve and starts feeling like a toll. The design would be stronger with less: fewer interlocking systems, faster power growth, and more stage variety to justify each new run.

Co-op: Four Armies, No Couch

The co-op model is ambitious. Ratatan gives each of up to four players their own Ratatan and Cobun squad, so every new player brings a whole army to the field instead of sharing control of one. For a game built around crowd-scale battles, that is the right choice, and the four-player mode draws praise.

The gap is just as clear: there is no local co-op, and the omission is a recurring complaint. Online rhythm play also needs strong netcode, because the genre depends on inputs landing exactly where the music says they should, and any game in this space has to get that right for co-op to work. The missing shared-screen option is harder to excuse. A side-scrolling game about drumming armies suits players sitting on the same couch. On Switch 2 especially, local multiplayer is a common way to play, and Ratatan does not support it.

Story and Pacing

The story follows a community of creatures traveling toward a mysterious goddess. A pilgrimage is a sensible backbone for a roguelike, because marching, falling and marching again feels like part of the journey rather than an arbitrary reset. The premise is light, which suits a game this focused on rhythm and crowd control. The risk is the one the grind makes worse: a journey only keeps its momentum if each stretch feels new.

The 1.0 Problem

The reception tells a specific story. The all-time Steam standing reflects enthusiasm for the concept across a long Early Access period. The recent turn reflects frustration that, according to players, the same problems survived into the full release. A game can recover from a rough launch, but leaving Early Access with problems players have been flagging since Early Access damages trust in a way that ordinary bugs do not. The foundation is strong. The finishing work is where Ratatan falls short.

The hand-drawn 2D animation is the most consistently praised part of the package, and the art direction suits the mechanics. Side-scrolling battles run left to right, which keeps even dense fights organized along a single line. That matters when a crowd of Cobuns has to read as one unit rather than a blur of sprites. Using small creatures as soldiers also softens a game that, mechanically, is about sending a mob into hostile ground again and again.

In a rhythm game, the soundtrack is part of the interface. The music is widely praised as catchy, and that has a practical benefit: tracks that are easy to learn make the beat easier to hold under pressure. The downside, as with the stages, is repetition. Music that every command depends on has to hold up when players hear it run after run.

The scale of the battles is also a performance risk. A 2D game is lighter on hardware than a 3D one, but a large crowd of animated characters plus effects is a real load, especially on portable hardware. In a rhythm game that matters more than usual: commands depend on timing, so any stutter that pulls the visuals out of sync with the audio damages the core loop directly.

• Steam (PC): This is where the game first launched, with Early Access running from September 2025 until the October 2026 full release. It is also where the reception split shows most clearly: Very Positive all-time user reviews against a much weaker recent average. Drum inputs suit a gamepad well, and timed key sequences should work on a keyboard too. A 2D game of this scope is light on hardware, but dense battles put more strain on portable hardware, so PC is the safer bet for players who care most about a steady beat.
• Nintendo Switch 2: Short, repeatable runs suit handheld play. The lack of local co-op stands out most on a console built around playing together in one room. Online co-op is the only multiplayer option, and dense battles sit less comfortably on portable hardware.

Ratatan gets the hard part right. Commanding a crowd through a drumbeat is an unusual idea that holds together, and the game turns it into a modern roguelike with handsome hand-drawn art and a co-op mode that gives every player an army. That foundation is real, and it is why the concept earned so much goodwill.

What holds it back is everything piled on top. The equipment grind and repetitive content date back to Early Access, and the sharp turn in recent user reviews suggests the 1.0 release did not fix them. The wider reception adds balance problems and overcomplicated systems. With no local co-op and a heavier load on portable hardware on top of that, the game falls short of the classic it follows. We recommend Ratatan to Patapon devotees and online co-op groups on PC who are prepared for a grind. Everyone else should wait to see whether post-launch updates can strip the systems back and let the beat lead again.
