A game’s mechanics and story may be its heart and soul, but the level design is the body that holds it all together. A well-designed level is more than just a series of rooms and corridors; it is a teacher, a guide, a storyteller, and a challenge all in one. It takes the game’s core principles and translates them into an experience that is both intuitive and engaging. A great level can make an average game feel spectacular, while a poor one can make even the best game feel frustrating and uninspired.
Over my years of developing and playing games, I’ve come to rely on a set of core principles that form the foundation of my level design philosophy. These are not just rules to follow, but rather a way of thinking about how a player will interact with the world you have built for them. Here are my top five principles of good level design.
1. The Player is Always a Student
Every game has a learning curve. A great level designer understands this and builds a world that teaches the player how to play, one lesson at a time. The first principle is to introduce new concepts and challenges in a safe, controlled environment before combining them or raising the stakes. Think of the early levels in classic games like Super Mario Bros., where a single Goomba is introduced before a series of them, or a single gap is shown before a complex jumping puzzle. This is known as a “soft tutorial.”
The level itself should be the teacher. You don’t need a pop-up text box telling the player how to jump; the level design should implicitly guide them to figure it out. For example, a small gap in the ground early on in a platformer prompts the player to jump to get across. The successful jump provides positive feedback, reinforcing the mechanic. Later, the same mechanic can be applied to a larger gap or a moving platform. By gradually increasing complexity, you prevent the player from feeling overwhelmed and build their confidence. This is not about making the game easy, but about ensuring the player has the necessary tools and understanding to overcome the challenges you present.
2. Create Flow and Pacing
A level should not be a continuous stream of identical actions. Imagine listening to a song that is just one loud, unchanging note—it would be a very unpleasant experience. Similarly, a game level needs variety and rhythm. The second principle is to control the player’s emotional and physical journey by balancing moments of high intensity with moments of quiet reflection.
Good pacing involves alternating between different types of gameplay. A tense combat encounter should be followed by a quiet section of exploration or a simple puzzle. This gives the player’s mind a chance to rest and process what has just happened. Moments of intense action—a chaotic firefight or a frantic chase sequence—build tension, while moments of exploration or narrative discovery provide a release. A level that is just a series of identical combat encounters will quickly become repetitive. A level that expertly balances action, puzzle-solving, and quiet narrative moments feels more like a complete and satisfying experience.
3. Guide the Player (Subtly)
One of the most frustrating things for a player is to feel lost. They should never have to wonder where to go next. The third principle is to use environmental cues to guide the player without a giant, glowing arrow pointing the way. This is known as using “visual language.”
There are many techniques to achieve this:
- Lighting: Use light to highlight a path, an exit, or an important object in a dark environment. A single lit torch on a wall can serve as a beacon, drawing the player’s eye and indicating the correct way forward.
- Color and Texture: Use a distinct color or texture to draw attention to a key object or a part of the environment that the player can interact with. A bright red valve in a muted, gray engine room will stand out and tell the player, “You need to interact with me.”
- Form and Silhouette: A unique shape or landmark visible from a distance can serve as a constant point of reference, helping the player to orient themselves within the larger world. A towering, distinct mountain or a unique building can act as a natural compass.
- Sound: Audio cues are just as important as visual ones. The distant sound of a waterfall or the echoing chime of a bell can subconsciously guide a player toward a specific location.
By using these subtle cues, you allow the player to feel smart and observant for figuring out where to go, instead of feeling like they are being hand-held.
4. Every Space Has a Purpose
A great level is a lean, efficient machine. Every room, corridor, and object serves a purpose, whether it’s functional, narrative, or aesthetic. The fourth principle is to eliminate filler. An empty room is not just an empty room; it’s a missed opportunity to tell a story, provide a challenge, or add to the atmosphere.
Before you add a new space to your level, ask yourself:
- Does this room serve as a combat arena?
- Does it contain a puzzle that the player must solve?
- Does it house an optional secret or an upgrade?
- Does it tell a piece of the game’s story through environmental storytelling (e.g., a deserted campsite with a half-eaten meal)?
If a space doesn’t serve a clear purpose, it should be re-evaluated. This doesn’t mean every space has to be a life-or-death challenge. A beautiful, serene room can serve the purpose of giving the player a moment of peace and rewarding them with a nice view after a tough fight. The goal is to make the player feel like no matter where they go, their journey is meaningful.
5. Reward Exploration and Curiosity
Players are naturally curious, and a good level design rewards that curiosity. The final principle is to give players a reason to veer off the main path. If the only way forward is a straight line, your world will feel flat and uninteresting.
Rewards don’t always have to be tangible. A secret, powerful weapon is a fantastic reward, but so is finding a hidden lore document that expands on the game’s story. It could also be a beautiful, scenic view that a player can only get to by doing some light platforming, or a simple Easter egg that provides a moment of delight. This makes the world feel more alive and personal, as if it is not just a stage for your game’s events, but a place with its own secrets and history. By rewarding exploration, you encourage players to engage more deeply with the world you’ve built, transforming a simple journey into a meaningful adventure.
In conclusion, level design is a challenging but incredibly rewarding discipline. By focusing on these five principles—teaching the player, controlling the pace, guiding them subtly, giving every space a purpose, and rewarding curiosity—you can build a world that is not only fun to play in but also memorable and impactful.
