The Design Process — Your Creative Roadmap! 🗺️¶
What Is the Design Process?¶
The Design Process = a step-by-step method for turning ideas into finished projects. Professional game developers, engineers, artists, and inventors ALL use it!
The 6 Stages¶
Reflection happens at EVERY stage! 🔄
Stage 1: IMAGINE — Dream Big! 💭¶
What Is Imagine?¶
Imagine = let your creativity run wild! No limits, no "that's impossible" — just pure ideas!
Imagine Activities¶
| Activity | Description |
|---|---|
| Brainstorm | Write 20 game ideas in 5 minutes |
| Mind Map | Central idea → branches of features |
| Mashup | Combine two games: "Mario + Tetris" |
| What If? | "What if gravity reversed?" "What if you played as the villain?" |
| Inspiration Board | Collect images, colors, music that inspire you |
Imagine Questions¶
| Question | Purpose |
|---|---|
| What's the core fun? | What makes the player smile? |
| Who is the player? | Kid, teen, adult, family? |
| What's the hook? | Why keep playing after 5 minutes? |
| What's unique? | What makes YOUR game special? |
| What's the feeling? | Joy, tension, wonder, mastery? |
Imagine Output¶
One-sentence Game Concept:
"A [genre] game where you [core action] to [goal] while [challenge], featuring [unique twist]."
Example:
"A platformer where you dash through time to collect chrono-shards while avoiding paradox monsters, featuring past/future world switching."
Stage 2: PLAN — Blueprint Your Game! 📐¶
What Is Plan?¶
Plan = turn your wild idea into a buildable blueprint with clear steps!
Plan Deliverables¶

Stage 3: CREATE — Build It! 🛠️¶
What Is Create?¶
Create = write the code, draw the art, record the sounds — make it real!
Create Best Practices¶
| Practice | Why |
|---|---|
| One thing at a time | Build movement, test, THEN add coins |
| Test constantly | Run after EVERY change |
| Use versioning | Save v0.1, v0.2, v0.3... |
| Comment your code | Future you will thank you |
| Clean up regularly | Right-click → Clean up |
Create Order (Suggested)¶
- Core movement (player controller)
- Camera follow (if scrolling)
- Ground collision (platforms)
- Collectibles (coins, score)
- Enemies (patrol, chase)
- Hazards (spikes, lava)
- Lives/Game Over (health system)
- Level transitions (broadcasts)
- UI (score, lives, timer)
- Sound effects (jump, coin, hit)
- Music (level themes)
- Polish (particles, juice, menus)
Stage 4: TEST — Does It Work? 🧪¶
What Is Test?¶
Test = systematically verify every feature works and find bugs!
Test Phases¶
| Phase | Focus | Who |
|---|---|---|
| Self-test | You play your own game | You |
| Target audience test | Kids play your game | Friends/siblings |
| Stress test | Push limits (100 clones, 30 min) | You |
| Edge case test | Weird inputs, rapid clicks | You |
| Regression test | Old features after changes | You |
Test Checklist¶
| Category | Specific Tests |
|---|---|
| Movement | All directions, speeds, jumping, edges |
| Collision | Ground, walls, ceilings, slopes, enemies |
| Collectibles | Score adds, sound plays, item disappears |
| Enemies | Patrol, chase, damage, defeat |
| Hazards | Spikes, lava, pits, falling |
| Lives | Lose life, invincibility, game over |
| Levels | Transitions, spawns, completion |
| UI | Score, lives, timer, menus, pause |
| Audio | Music loops, SFX volume, mute |
| Performance | 100 clones, 30 min, save/load |
Test Documentation¶
TEST LOG - v0.5
===============
Date: 2026-06-10
Tester: Me
PASSED:
✅ Player moves left/right smoothly
✅ Jump works from ground only
✅ Coin collection adds 10 points
✅ Enemy patrol turns at edges
FAILED:
❌ Player gets stuck in wall corner
❌ Enemy sometimes walks through platform
❌ Music doesn't loop properly
NOTES:
- Wall sticking: need better corner collision
- Enemy: check ground detection
- Music: check loop points
Stage 5: IMPROVE — Make It Better! ⬆️¶
What Is Improve?¶
Improve = fix bugs, add polish, balance difficulty, add "juice"!
Improvement Categories¶
| Category | Examples |
|---|---|
| Bug Fixes | Wall sticking, enemy clipping, music loops |
| Balance | Enemy speed, jump height, coin values |
| Juice | Screen shake, particle effects, screen flash |
| Accessibility | Colorblind mode, adjustable speed |
| Quality of Life | Checkpoints, level select, skip cutscene |
| Performance | Reduce clones, optimize loops |
The "Juice" Checklist 🍹¶
| Juice Element | Implementation | Impact |
|---|---|---|
| Screen shake | change x by (pick random -5 to 5) on hit |
Impact feel |
| Screen flash | change color effect by 50, wait, clear |
Damage feedback |
| Particle burst | Clones + stamp + fade on collect/hit | Satisfaction |
| Sound variation | pick random pitch on repeated SFX |
Less repetition |
| Screen pause | wait 0.05 secs on big events |
Weight/impact |
| Coyote time | Allow jump 0.1s after leaving ground | Forgiving jumps |
| Jump buffering | Queue jump if pressed slightly early | Responsive feel |
Balancing Difficulty¶
| Too Easy | Too Hard | Just Right |
|---|---|---|
| Enemies never hit | Instant death traps | Fair challenge |
| Infinite lives | One-hit kills | 3 lives + checkpoints |
| No time pressure | Impossible time limits | Generous but present |
| Boring repetition | Impossible jumps | Variety + progression |
Iterative Development — Cycle Until Perfect! 🔄¶
Each cycle makes the game better! Most pro games go through 50+ iterations.

Reflection — Learn and Grow! 🧠¶
What Is Reflection?¶
Reflection = looking back at your project to learn what worked, what didn't, and how to improve next time!
Reflection Questions¶
| Question | Purpose |
|---|---|
| What am I most proud of? | Celebrate success |
| What was hardest? | Identify learning gaps |
| What would I do differently? | Improve process |
| What did I learn? | Cement knowledge |
| What's next? | Plan future projects |
Reflection Template¶
PROJECT REFLECTION
==================
Game: [Name]
Version: [v1.2]
Date Completed: [Date]
WHAT WENT WELL:
- Smooth player movement felt great
- Enemy AI was challenging but fair
- Juice effects made collecting coins satisfying
- Music fit the theme perfectly
CHALLENGES OVERCOME:
- Wall sticking bug → fixed with raycast collision
- Enemy AI too aggressive → tuned detection radius
- Music looping click → fixed with seamless loop points
WHAT I LEARNED:
- Broadcast and wait is essential for level loading
- Variable scope (global vs local) matters a lot
- Juice effects make huge difference in feel
- Testing with actual kids reveals real issues
NEXT TIME I'LL:
- Plan asset list more carefully upfront
- Use versioning from day 1 (lost v0.3!)
- Add automated tests for core mechanics
- Design juice effects earlier in process
NEXT PROJECT IDEAS:
- Metroidvania with map system
- Multiplayer co-op platformer
- Level editor for players
