What Is a Metroidvania? The Exploration and Progression Design Behind Lelu

By VGSources Team 8 min read

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

A Metroidvania is an exploration-focused action-adventure built around a connected world that opens gradually. You encounter a barrier, discover an ability, tool or piece of knowledge, then return with new options to reach places that previously seemed impossible. The reward is not just a stronger character: it is a world that has become larger and more intelligible.

Lelu applies that design idea to an in-development monochrome toy-factory adventure. Its announced ingredients—puzzles, traps, conveyor belts, electrified circuits, sentient toys, clockwork titans, hidden abilities and secrets—fit the broad Metroidvania pattern. The final map, ability sequence, release build and other details are not yet established, so Lelu is best described as an announced, top-down or dungeon-crawler-leaning Metroidvania rather than a finished example of every genre convention.

What the term “Metroidvania” means

“Metroidvania” combines the names of Metroid and Castlevania. It points to the exploratory structure associated with Metroid and the interconnected-castle progression popularized by Castlevania: Symphony of the Night. The word is a practical design label, not an official genre standard. No governing checklist decides whether a game qualifies.

At its center is a relationship between space and progression. The world is connected or meaningfully interrelated, and progress changes what parts of that world the player can use. A new capability may open a route, reveal a secret, make a hazard survivable, solve a puzzle or provide the knowledge needed to interpret an earlier clue. Exploration is therefore cumulative: the player remembers places as well as collecting items.

  • Join Samus Aran in the first new 2D Metroid story in 19 years
  • Explore planet ZDR’s many environments as you investigate a mysterious transmission
  • Deadly E.M.M.I. robots, research machines, pose a threat more intense than ever
  • Feel Samus’ power grow as you gain maneuvers and abilities like the new Spider Magnet
  • Power up and return to previous areas to find new paths and secrets

A game does not need every familiar feature to be recognizably Metroidvania. Side-scrolling presentation, real-time combat, bosses, role-playing statistics, fast travel, collectibles and multiple endings are common choices, but none is mandatory. A top-down game can fit the pattern if its world, gates and upgrades create the same exploration-and-revisitation relationship.

The five-part progression loop

Most Metroidvanias can be understood as a repeating loop. Each stage has a different job in the player’s decision-making.

1. Explore a connected space

The player moves through rooms, corridors, towers, caverns or outdoor zones that relate to one another. Exploration teaches the layout: where routes split, which landmarks identify a district, where save points or shortcuts sit, and which paths appear suspicious. The player is not simply clearing isolated levels; they are building a mental model of a place.

2. Meet a gate

A gate is anything that blocks progress or makes a route impractical. It can be a locked door, a gap too wide to cross, a high ledge, an electrical hazard, a hostile creature, a puzzle, a breakable obstruction or a passage whose meaning is unclear. A gate creates a question rather than ending exploration: what would make this route possible?

3. Acquire a capability

The answer is usually a permanent ability, tool, weapon, upgrade or usable knowledge. Movement powers change where the character can go; tools interact with particular objects; weapons may defeat a barrier or enemy; survivability upgrades let the player endure an environment; information can reveal a code, pattern or route. The important property is not rarity but changed possibility.

4. Revisit with new affordances

Returning to an earlier area matters because the player can now cross, break, activate, survive or understand something that was previously out of reach. The same room is transformed by the player’s new options. Good design makes the revisit legible through landmarks and rewards rather than treating it as an arbitrary fetch trip.

5. Receive a meaningful reward

The reward may be a new region, a shortcut, an optional room, a secret, a story discovery, a boss encounter, an upgrade or a collectible. The strongest rewards reinforce the loop by giving the player another capability or a reason to inspect the world again.

What is essential, and what is optional?

The following distinction helps separate the genre’s structural core from its frequently used decoration.

Feature Status Why it matters
Connected or meaningfully interrelated world Essential Routes and regions must relate so that earlier knowledge remains useful.
Progression that changes access Essential New capabilities alter which spaces or challenges are possible.
Abilities, tools, equipment or knowledge as keys Essential The player gains a practical answer to previously encountered barriers.
Exploration and revisitation with rewards Essential Returning to known spaces produces discovery rather than mere repetition.
Side-scrolling camera Common, not required It supports platforming gates, but top-down and other views can use the same structure.
Real-time combat and bosses Common, not required Combat can supply danger and progression, but puzzles or traversal may carry more weight.
Map screen, fast travel, collectibles, RPG statistics or multiple endings Optional These systems support navigation or customization but do not define the category.

Why gates and backtracking are the heart of the experience

Gates create curiosity

A well-placed gate communicates possibility. A ledge that is visibly just beyond reach, a sealed door with a recognizable mechanism or a corridor filled with a hazard gives the player a concrete future objective. The gate should be understandable without revealing the entire solution. If it is invisible, arbitrary or repeated too often, it feels like a technical restriction instead of an invitation to explore.

Gates can be layered. A door may require a tool, while the room beyond requires a movement ability and a puzzle solution. This layering lets designers control pacing without dividing the world into disconnected stages. It also gives players several simultaneous questions, so finding one answer does not end the larger investigation.

Backtracking turns memory into progress

Backtracking is not automatically good or bad. It is valuable when the player’s return changes the meaning of a place, exposes a shortcut or offers a reward that justifies the trip. It becomes burdensome when the route is long, empty and unchanged, especially if the game provides no map landmarks, shortcuts or fast-travel option.

Rank #2
Metroid Prime Remastered - Nintendo Switch
  • Become intergalactic bounty hunter Samus Aran and explore an alien planet in this critically-acclaimed first-person adventure
  • Use and upgrade abilities like the Morph Ball, Missiles, and an array of beams to survive the harsh environments and lethal creatures of the planet Tallon IV
  • Gain abilities and revisit areas to uncover the different routes and secrets hiding in a beautiful-yet-threatening interconnected world
  • Scan your surroundings to gather information about the planet’s history and the creatures that call it home or to reveal enemies’ weak points
  • Choose from multiple control options and experience revamped graphics, sound, and unlockable art in this remastered classic

Designers manage that burden through compact loops, elevators, doors that open from the far side, teleport points, clear visual landmarks and maps that mark unresolved possibilities. The objective is not to eliminate revisits but to make each revisit feel like informed route planning.

Maps teach the player how to think

Nintendo’s official material for Metroid Dread describes “the map—the foundation of exploration” as a major design focus. The map is more than a convenience: it records relationships the player has discovered and helps turn a vague memory into a plan. Nintendo also notes that, with this kind of progression, players may look at paths and barriers “in a different light.” A previously blocked route becomes a future destination rather than background scenery.

Map quality depends on more than drawing rooms. Useful orientation support includes distinctive landmarks, readable room connections, indicators for unexplored branches and a way to distinguish a discovered secret from an unopened possibility. Some games deliberately withhold markers to encourage memory; that is a presentation choice, not a requirement of the genre.

Is Lelu a Metroidvania?

Based on the announced material, yes in the broad design sense. Lelu is an in-development monochrome action-adventure by Jamie Rowan associated with Super Rare Originals. Its official Steam description presents a single-player journey through a toy factory arranged as a labyrinthine tower. The listing names puzzles, traps, conveyor belts, electrified circuits, sentient toys, clockwork titans, hidden abilities, secrets and other toys seeking freedom. Steam uses the “Metroidvania” tag, while the developer’s itch.io page describes the project as a “1-bit” dungeon crawler and Metroidvania.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Super Rare Originals’ July 15, 2026 showcase announcement calls Lelu a “black and white metroidvania” and says a demo is available to try. The Steam listing describes the full game as “Coming soon.” No stable final release date is established by those materials.

How Lelu matches the genre’s core

  • Exploration: A toy-factory labyrinth supplies an interconnected setting to learn and revisit.
  • Gates: Puzzles, traps, conveyor systems and electrified circuits can function as environmental or problem-solving barriers.
  • Capabilities: The announced hidden abilities imply permanent changes to what the player can do and reach.
  • Rewards: Secrets, liberated toys, new routes and story discoveries provide reasons to investigate beyond the critical path.
  • Presentation: Its monochrome, top-down or dungeon-crawler-leaning identity distinguishes it from side-scrolling examples without excluding it from the broader pattern.

The store description also calls the protagonist “a small but determined clockwork toy who has gained consciousness and found a taste for freedom!” That is flavor copy from the official listing, not independent critical evaluation, but it establishes the premise and tone.

What remains unconfirmed

Available announcements do not establish the final world topology, the number or order of abilities, total playtime, boss structure, release build, sales, review score or whether every classic convention will appear. It is therefore more accurate to describe Lelu as an announced example of the Metroidvania idea than to claim a finalized blueprint. Its confirmed differentiators are the black-and-white presentation, toy-factory setting, puzzle-and-trap emphasis, clockwork enemies and top-down or dungeon-crawler positioning.

How to evaluate a Metroidvania beyond the label

“Metroidvania” covers games with very different rhythms. These questions reveal what a particular title actually asks of you.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
Question What to examine
How connected is the world? Is it one interlocking space, linked rooms or mostly separate stages?
What kind of gates dominate? Movement abilities, tools, combat strength, puzzles, story events or knowledge?
What do upgrades change? Movement, combat, puzzle-solving, survivability or several at once?
How demanding is backtracking? Does returning produce discovery, efficient route planning or repetitive cleanup?
How does the game support orientation? Maps, landmarks, shortcuts, save points and fast travel all affect cognitive load.
What do optional rooms provide? Meaningful abilities, lore, shortcuts, collectibles or only minor resources?
What is the presentation? Side-scrolling platforming, top-down navigation, isometric space or another camera model?

These axes explain why two games can share the label while feeling unlike each other. One may make precise movement the main gate; another may use combat builds or environmental puzzles. The common thread is that the world responds to acquired capabilities.

A canonical starting point

Metroid Dread for Nintendo Switch is a useful modern, physical example of the form. It presents a map-centered exploration structure in which new items and weapons alter how players understand paths and barriers. It is best used as a reference point for the design pattern, not as a substitute for Lelu. Availability, price and any promotional terms for a physical copy can change by region and date.

Common mistakes when describing the genre

  • Calling every exploration game a Metroidvania: A large map alone is insufficient; progression must meaningfully change access.
  • Treating “backtracking” as a flaw by definition: The relevant question is whether revisits produce new information, routes or rewards.
  • Assuming side-scrolling is mandatory: Camera perspective is optional when the gate-and-capability structure remains intact.
  • Confusing a demo with the finished design: An in-development game can demonstrate the concept while leaving its final map, pacing and content unsettled.
  • Using the label as a promise of specific features: The term does not guarantee bosses, fast travel, statistics, collectibles or multiple endings.

The clearest definition is also the most practical: a Metroidvania makes exploration itself a form of progression. You learn a connected place, encounter a barrier, gain a lasting new option and return to discover that the place has changed.
