Kotama and Academy Citadel

The Metroidvania shelf is overcrowded, and the genre’s best entries have trained players to expect three things: a map worth getting lost in, movement that is satisfying in its own right, and fights that test more than button endurance. Kotama and Academy Citadel, a 2.5D side-scroller from developer Atomstring Games and publisher 2P Games, bets most of its chips on the third.

The premise swaps the usual ruined castle or dying kingdom for Carmel, a high-tech academy built on a blunt meritocracy where strength determines who succeeds. Kotama arrives as an exchange student chasing the “Carmel Star”, the school’s most prestigious honor, and the citadel that houses the academy becomes the labyrinth. It is a smart framing device. A school that ranks students by power gives every boss a reason to exist and every upgrade a narrative justification. It also gives the game an anime-adjacent identity that separates it from the gothic and pixel-art crowd.

In market terms, this is an affordably priced, mid-scale entry aimed at players who care about combat feel. Steam reception is positive, while critic aggregates land in solid-but-not-spectacular territory; Metacritic sits at 76. The praise in that coverage clusters around the fighting, the bosses and the art; the complaints cluster around everything between fights. Critics measuring the game against the genre’s top tier found a conservative, mostly linear structure and a story that doesn’t hold together. Recent Steam reception has softened, worth watching rather than a red flag.

The package is single-player only, ships on Windows and SteamOS + Linux, and offers full audio and subtitles in multiple languages, including English and Japanese. That last detail matters more than it looks. Full Japanese audio is a real draw for the audience this art style courts, and it signals a localization budget many small Metroidvanias skip.

• Switchable weapon combat: Fast, combo-driven fighting built around swapping weapons, with a design that rewards adapting to each encounter over reckless aggression.
• Parry and bullet-time boss fights: Bosses demand timing and precision, with parrying and slowed-time mechanics at the center of the action.
• Fluid-based abilities: Kotama’s toolkit uses fluid-based powers to get past the obstacles and traps that gate progress through the citadel.
• A vast, labyrinthine citadel: The academy’s sprawling interior serves as the interconnected map, opened up in genre tradition as new abilities arrive.
• Ally-driven story choices: Companions met along the way make choices that can change how the narrative unfolds.
• Wide difficulty range: Settings run from relaxed to highly challenging, covering genre newcomers and veterans alike.
• Steam extras: Achievements, Trading Cards, Cloud saves, and multiple-language full audio and subtitles.

Combat: The Reason to Show Up

Combat is where the design’s priorities are clearest. A switchable-weapon system in a combo-driven action game lives or dies on one question: does the game punish monotony? The stated design goal of rewarding adaptation over rushing in suggests it does, and the critical praise for weapon switching indicates the system delivers on that intent. This is the right philosophy. Too many Metroidvanias hand players a sword in the first minute and a slightly bigger sword ten hours later. A swap system that changes how an enemy must be approached turns each encounter into a small problem of spacing, loadout and timing, instead of a stamina check.

The risk in front-loading a game’s intelligence into its combat is that the surrounding systems end up thin, and the critical consensus flags exactly that: underdeveloped systems. When fighting is the most developed layer, every lighter one around it shows. A deep combat model wrapped in shallow progression caps how long the loop stays fresh, because the incentive to experiment eventually depends on the game giving players new reasons to.

Bosses: Parry, Bullet Time and Reading Tells

Putting parry and bullet time together at the center of boss design is a clear statement of intent. A parry rewards reading an attack’s windup; slowed time stretches the moment in which that read becomes punishment. Together they push boss fights toward the pattern-recognition school of action design, where an encounter is learned and then executed rather than out-leveled.

That structure explains why bosses draw so much of the praise. Precision-gated fights produce the genre’s most memorable highs: the encounter that takes twenty attempts and then clicks all at once. They also produce its steepest walls, which is where the difficulty range earns its place. Offering settings from relaxed to highly challenging means a parry-heavy boss doesn’t have to act as a hard filter on who reaches the credits.

Exploration: Labyrinth in Name

Here the design stumbles. The citadel is pitched as vast and labyrinthine, and the map’s scale draws praise, yet critical coverage describes the structure as conservative and mostly linear. Those claims aren’t contradictory, since a map can be large without branching much, but together they mark the gap between this game and the genre’s leaders. The best Metroidvanias make the map itself the puzzle: sequence breaks, optional routes, the realization that one new ability opens three old doors. A mostly linear citadel trades that discovery for direction. Newcomers may welcome the guidance; veterans will feel the guardrails.

Traversal is also where the friction concentrates. Rough platforming and frustrating difficulty during exploration recur in the complaints, and that is a structural problem for this genre specifically, because a Metroidvania asks players to spend as much time moving between fights as inside them. The fluid-based abilities should be the connective tissue between combat set pieces. If trap corridors and jumps are less precise than the fighting, pacing sags between the highs. Notably, coverage praises the game’s fluid movement while criticizing its platforming, which points less at the character controller and more at the obstacle courses built around it.

Story and Allies

The academy premise is strong; the execution, per the critical record, is weak or inconsistent. Allies whose choices can shift the story is an ambitious feature for an action-first Metroidvania, and it gives the cast a reason to matter beyond their portraits. But branching narrative only pays off when the base story is coherent enough to make its branches worth caring about. A setting where strength decides success invites pointed commentary on power and status, and a plot that loses its thread wastes that opening. The story is best treated as framing for the fights, not the reason to keep going.

Difficulty and Accessibility

The relaxed-to-highly-challenging spread is a sound commercial and design decision, and it pairs naturally with a linear structure that keeps newcomers from getting lost. The catch is where the frustration complaints land. Difficulty settings in action games traditionally tune enemy damage and health far more readily than they reshape a trap-laden corridor, so exploration friction is the part of this game least likely to bend to a lower setting.

The 2.5D presentation places 3D-rendered characters and environments on a 2D plane, and the art, animation and character portraits all earn consistent praise. The high-tech academy aesthetic gives the game a visual identity distinct from the genre’s crumbling castles and moody caverns, and the portrait work gives the ally cast personality in dialogue, which matters for a story built around their choices.

Animation carries functional weight here. In a parry-centric game, attack windups are the UI: a boss’s telegraph has to read clearly at speed, or the parry system turns into guesswork. The praise for animation is a good sign on that front. A combo system with switchable weapons also places demands on the HUD, since the active weapon and available options need to register at a glance in the middle of a fight.

A 2.5D side-scroller of this scope is built for modest hardware demands. Critical coverage does cite some technical and polish issues, so rough edges should be expected rather than ruled out.

The game is a Steam-only release covering Windows and SteamOS + Linux:

• Windows and SteamOS + Linux: Both are supported directly. macOS is not listed.
• Input: Precision-timed action of this type is controller-shaped by nature. Desktop players should plan on a gamepad for the boss fights.
• Cloud saves: Progress can move between supported devices, which suits a game whose bosses invite repeated short attempts.
• Steam features: Achievements and Trading Cards are included across the board.
• Parity and pricing: A single storefront means one build and no version fragmentation. At $14.99, the value case rests on how much weight a player puts on combat over exploration.

Kotama and Academy Citadel knows exactly what it does best, and it builds the game around it. The weapon-switching combat and the parry-driven bosses give it a clear reason to exist in a crowded genre, and the art direction and academy setting give it a face that won’t be mistaken for its competitors. Those strengths explain the warm Steam reception and the respectable critic score.

What holds it back is everything between the fights. The platforming is the weak link in a genre that leans heavily on movement, the citadel’s scale masks a conservative structure, and the story fumbles a premise with real potential. These are not fatal flaws, but they cap the ceiling. This is a combat-forward action game with a competent but thin Metroidvania shell.

We recommend it narrowly to players who come to the genre for combat and bosses, especially at its affordable price. Players who prize exploration and tightly designed platforming should temper expectations, because the map is where this game loses its edge.
