10 Tips for Mastering Level Design in 2D Platformers

Designing levels for 2D platformers is a delicate art that requires a combination of creativity, player psychology, and technical understanding. A well-designed level can keep players engaged, challenge them without overwhelming them, and create a sense of accomplishment. Whether you are an aspiring game designer or a seasoned developer looking to refine your craft, this guide provides 10 essential tips for mastering level design in 2D platformers.

Understand the Core Mechanics

The first step to creating great levels is understanding the core mechanics of your game. Every platformer has a set of rules that define how the player interacts with the world. These mechanics could include running, jumping, wall-jumping, double-jumping, or the ability to interact with objects or enemies.

Key Focus Areas:

• Mastery Curve: Introduce the mechanics gradually to allow players to understand and master each new ability or action.
• Challenge Progression: Start simple and increase the difficulty level at a steady pace. A level that feels too hard or too easy can disrupt the player's engagement.

Example:

In games like Super Mario Bros., the first few levels focus heavily on teaching players how to jump and avoid simple obstacles. As the game progresses, new mechanics (like power-ups or more complex enemy patterns) are introduced in a way that builds on previous knowledge.

Create Meaningful Flow

Flow is a key concept in game design, referring to the smooth progression from one obstacle to the next. In platformers, this means that the player should never feel like they are stuck or aimlessly wandering. Instead, they should always have a clear sense of direction.

Key Focus Areas:

• Visual Cues: Use the environment to direct the player's attention. Arrows, lighting, or even the design of platforms can subtly guide the player's movement.
• Pacing: Mix up slower, more thoughtful sections with faster-paced action. Varying the tempo keeps the gameplay interesting and allows players to anticipate new challenges.

Example:

In Celeste, the level design uses visual cues like changes in background colors and lighting to indicate the next area of interest. The player is constantly aware of where they are and where to go next, which helps maintain a steady flow.

Teach Through Design, Not Text

One of the key principles of great level design is that the environment should teach the player what to do, without the need for lengthy tutorials or text boxes. Players should learn about the game's mechanics and obstacles by interacting with the environment itself.

Key Focus Areas:

• Early Levels as Training Grounds: Early levels should focus on teaching the core mechanics, and every challenge should serve as a lesson in using those mechanics effectively.
• Non-Linear Learning: Not every challenge needs to be presented in a strictly linear fashion. You can encourage exploration and discovery by offering players multiple ways to approach a problem.

Example:

In Super Meat Boy, the early levels introduce the player to jumping, dodging, and timing without using any text. Each level is a micro-tutorial, teaching players through trial and error.

Design for Precision and Control

Precision is at the heart of many 2D platformers, and as such, it's crucial to design levels that give players precise control over their actions. A level that feels too slippery or difficult to control can frustrate players and break the immersion.

Key Focus Areas:

• Tight Controls: Ensure that the character's movement is responsive. The player should feel like they are in control at all times.
• Well-Designed Platforms: Platforms should be designed so that jumps feel satisfying. Avoid overly narrow or unfair platforms, and give players enough room to land or adjust mid-jump.

Example:

Shovel Knight is a great example of a platformer where the controls feel tight and responsive, allowing players to make precise jumps and movements. The levels are designed to challenge players, but the character's movement feels fluid enough to handle those challenges.

Introduce Varied Obstacles and Enemies

A great level keeps players on their toes by introducing a wide variety of obstacles and enemies that require different strategies to overcome. Repetition can make gameplay feel monotonous, so it's important to keep things fresh.

Key Focus Areas:

• Obstacle Types: Mix in different types of hazards like moving platforms, spikes, enemies, and environmental dangers (e.g., water or fire).
• Enemy Behavior: Make enemies behave in a way that complements the level design. Some enemies might charge at the player, while others might patrol in a set pattern. Create situations where the player has to plan their movements accordingly.

Example:

In Donkey Kong Country, the levels are full of different hazards, from swinging ropes to rolling barrels, requiring the player to learn different approaches for each situation. The variety ensures the gameplay stays dynamic and exciting.

Provide Safe Zones for Rest and Reflection

A common pitfall in platformer design is a lack of breaks. When levels are constantly challenging the player with no chance to rest, it can become overwhelming. Incorporate "safe zones" where players can pause, reflect, or simply appreciate their progress.

Key Focus Areas:

• Rest Areas: These can be as simple as a few seconds of downtime between difficult sections, allowing the player to breathe and prepare for the next challenge.
• Environmental Storytelling: Use safe zones to tell a story or reinforce the theme of the game, allowing players to reflect on their journey so far.

Example:

In Hollow Knight, the "safe zones" are areas where the player can rest, save their progress, and enjoy a break from the intense action. These areas also offer a moment for players to reflect on the world they are exploring.

Use Verticality to Add Depth

One of the main advantages of 2D platformers is the ability to create levels with layers of verticality. This can make a level feel more dynamic and complex, offering players more ways to approach challenges.

Key Focus Areas:

• Multiple Pathways: Design levels with both horizontal and vertical movement in mind. Offer players different routes, some of which may be more difficult but provide greater rewards.
• Zoning and Layering: Use verticality to create levels that feel multi-dimensional. For example, players might need to jump between platforms or climb walls while avoiding enemies.

Example:

In Rayman Legends, many levels are designed with significant verticality. Players can explore different levels by climbing walls, jumping between platforms, and discovering hidden paths, which keeps the gameplay exciting and encourages exploration.

Incorporate Environmental Interaction

Environmental interaction can make a platformer feel more dynamic. Allowing players to manipulate the environment---whether by moving blocks, opening doors, or activating switches---adds a layer of depth to the game.

Key Focus Areas:

• Interactive Objects: Introduce objects that players can move, destroy, or use to interact with the environment. These objects should be integrated into the level design in a way that feels natural and rewarding.
• Puzzles and Secrets: Use environmental interactions to introduce puzzles or hidden areas that reward players for exploration and problem-solving.

Example:

In Braid, players must manipulate time and objects in the environment to solve puzzles. The levels are designed to make these interactions feel essential, blending the environment with the platforming mechanics.

Test and Iterate Based on Player Feedback

Designing levels isn't a one-and-done process; it requires constant testing and iteration. Even experienced designers can miss potential issues that only become apparent during playtesting.

Key Focus Areas:

• Playtesting: Always test your levels with real players to identify problem areas. Watch how players interact with the environment and take note of where they get stuck or frustrated.
• Feedback Loops: Use player feedback to refine and adjust your levels. Don't be afraid to make changes if something isn't working.

Example:

Many indie developers of platformers like Celeste and Super Meat Boy rely heavily on player feedback to fine-tune the level design. This iterative process ensures that the levels are not only fun but also appropriately challenging.

Maintain a Consistent Visual Style

A consistent visual style helps tie the entire game together and ensures that players can quickly identify important elements in the environment. Whether it's the design of the platforms, enemies, or hazards, maintaining a coherent aesthetic helps with immersion and clarity.

Key Focus Areas:

• Visual Contrast: Make sure there's enough contrast between the player character and the background so they are easy to see and interact with. Similarly, hazards and interactive elements should stand out clearly.
• Theme and Environment: Keep the theme and setting consistent throughout the game. Whether it's a jungle, castle, or futuristic city, ensure that the visual style reflects the tone and story of the game.

Example:

In The Messenger, the levels have a consistent pixel art style that reflects the game's retro aesthetic. The environments are visually distinct, but they all maintain the same cohesive look, helping to guide the player through the world.

Conclusion

Mastering level design in 2D platformers requires a balance of creativity, technical skill, and player-centric thinking. By focusing on the flow, pacing, and interaction of the environment, you can create levels that are both challenging and enjoyable. Remember to iterate based on player feedback and constantly refine your designs to ensure that each level provides a unique and rewarding experience. With these 10 tips in mind, you'll be well on your way to creating compelling and engaging levels that keep players coming back for more.
