## Workflow

### Phase 1: HUD Analysis

```
INFORMATION PRIORITY
+------------------+----------+-----------+
| Information      | Priority | Display   |
+------------------+----------+-----------+
| Health/Lives     | CRITICAL | Always    |
| Score/Progress   | HIGH     | Always    |
| Objectives       | MEDIUM   | Context   |
| Inventory        | LOW      | On demand |
+------------------+----------+-----------+
```

### Phase 2: Feedback Design

```
ACTION -> FEEDBACK MATRIX
+-------------+--------+-------+--------+
| Action      | Visual | Audio | Haptic |
+-------------+--------+-------+--------+
| Hit enemy   | Flash  | Impact| Pulse  |
| Get hit     | Red    | Pain  | Strong |
| Collect     | Pop    | Chime | Light  |
| Level up    | Burst  | Fanfare| Long  |
+-------------+--------+-------+--------+
```

### Phase 3: Onboarding

```
PROGRESSIVE TEACHING
- Stage 1: Movement (safe space)
- Stage 2: Core action (easy target)
- Stage 3: Advanced mechanic (contextualized)
- Stage 4: Combination (designed challenge)

RULE: No text walls. Learn by DOING.
```
