# Game Design

## Core design principles

### Game mechanics

The rules and systems defining player interaction.
**Core loop:** The repeated action cycle. Run → Jump → Collect → Return.
**Feedback loops:** Positive (snowball effect), Negative (catch-up mechanics).
**Emergence:** Complex behavior from simple rules. Chess, Minecraft.

### Player psychology

**Flow state (Csikszentmihalyi):** Challenge matches skill level. Not too hard, not too easy.
**Intrinsic motivation:** Autonomy (player choice), Mastery (skill growth), Purpose (meaning).
**SNED framework:** Sensation, Fantasy, Narrative, Challenge, Fellowship, Discovery, Expression.
**Loss aversion:** Losing feels twice as bad as equivalent gain feels good.

## Level design

**Tutorial design:** Teach through play, not through text. Portal's first chamber.
**Affordances:** Visual cues that suggest use. Glowing objects = interact.
**Pacing:** Mix intensity. Intense combat → exploration → puzzle → boss.
**Rule of three:** Introduce mechanic → add complication → combine with other mechanics.

## Game balancing

**Zero-sum vs positive-sum:** Competitive balance vs cooperative/single-player balance.
**Economy design:** Sources (gain resources) and sinks (spend resources). Must balance.
**Difficulty curves:** Tutorial flat, then gradually increase with spikes for bosses.
**Playtesting:** Test with real players, not developers. Watch — don't explain.

## Narrative design

**Ludonarrative dissonance:** When mechanics conflict with story. Nathan Drake kills 1000 enemies but is "good person."
**Environmental storytelling:** Narrative through world detail without cutscenes.
**Player agency:** Choices with meaningful consequences.

## Unity vs Godot

### Unity (most used commercially)

**C# scripting.** Asset Store. Massive community.
Unity Learn: Free, extensive beginner to advanced tutorials.

```csharp
void Update() {
    float moveX = Input.GetAxis("Horizontal") * speed * Time.deltaTime;
    transform.Translate(moveX, 0, 0);
}
```

### Godot (free, open source, MIT license)

GDScript (Python-like) or C#. Lightweight. Best for 2D.
Free. No royalties. Excellent for indie developers.

```gdscript
func _process(delta):
    var direction = Input.get_axis("ui_left", "ui_right")
    position.x += direction * speed * delta
```
