Level Design Principles

Flow

Players should move through the space with purpose:

• Clear paths - Intuitive routes between areas
• Multiple options - No single "correct" way
• Decision points - Players choose their path
• Risk gradient - Danger increases with reward

Landmarks

Players should orient themselves easily:

• Silhouettes - Distinct visual shapes
• Lighting - Key areas highlighted
• Audio cues - Sounds indicate location
• Unique features - Memorable elements

Pacing

Match the intended experience:

• Buildup - Start slow, increase intensity
• Peaks - High-tension moments
• Breathing room - Brief downtime
• Climax - Final push to objective

Level Design Process

Step 1: Concept Sketch

Create a rough layout showing:

• Overall shape
• Major zones
• Key landmarks
• Spawn/extract points

Step 2: Zone Definition

Define each area by:

• Primary purpose
• Risk level
• Loot quality
• Flow role

Step 3: Connection Design

Create paths between zones:

• Main routes (obvious)
• Alternative routes (hidden)
• Shortcuts (risk/reward)
• Choke points (conflict areas)

Step 4: Loot Placement

Place rewards following:

• Risk gradient (deeper = better)
• Exploration reward (off-path = bonus)
• Flow guidance (loot attracts movement)
• Balance considerations (not all in one spot)

Step 5: Playtest Validation

Test and iterate:

• Do players flow as intended?
• Are there camping spots?
• Is loot distributed fairly?
• Are spawns safe?

Common Level Patterns

Arena

Symmetrical, focused on fair competition:

• Central conflict zone
• Mirrored starting positions
• Clear sightlines
• Equal distance to objectives

Linear

Progressive, narrative-driven:

• Clear forward path
• Branching side areas
• Setpiece encounters
• Progressive difficulty

Open World

Exploration-focused:

• Non-linear progression
• Multiple objectives
• Fast travel points
• Dynamic events

Hub and Spoke

Central base with destinations:

• Central safe zone
• Radiating paths
• Distinct themed areas
• Return to hub mechanic

JSON Level Data Format

Standard Level JSON Structure

When implementing levels in JSON format for Phaser 3 games:

{
  "id": "level001",
  "name": "Tutorial - First Shot",
  "description": "Learn the basics with an impossible-to-fail tutorial shot",
  "birds": ["red", "red", "red"],
  "starThresholds": {
    "one": 5000,
    "two": 32000,
    "three": 72000
  },
  "pigs": [
    { "x": 800, "y": 500, "type": "small" }
  ],
  "blocks": 
             
  
      
        

Level Design Best Practices for JSON

1. Progressive Difficulty

   • Early levels: Tutorial patterns, single solution
   • Mid levels: Multiple valid approaches
   • Late levels: Complex structures requiring mastery

2. Star Threshold Formula

   2-star: 30,000 + (level × 2,000)
   3-star: 60,000 + (level × 6,000)
   

3. Bird Allocation

   • Tutorial levels: 3 birds (fail-proof)
   • Practice levels: 3-4 birds
   • Complexity levels: 4-5 birds
   • Mastery levels: 5-7 birds

4. Validation Checklist

   • All x/y coordinates within world bounds
   • All material types are valid (glass, wood, stone, explosive)
   • All pig types are valid (small, medium, large)
   • All bird types are valid (red, yellow, black, white, blue)
   • Star thresholds follow progressive formula
   • At least 2 valid solutions exist
   • Level is solvable within bird count

Level Documentation Template

Level Review Checklist

Before marking a level complete:

• Layout supports target player count

• Landmarks provide orientation
• Choke points have counterplay
• Performance is acceptable
• Art style is consistent
• JSON format is valid
• Coordinates are within bounds
• Materials and types are valid
• Star thresholds follow formula
• Multiple solutions exist
• Level is solvable
