+- **File Operations**: Implemented fallback mechanisms for missing or corrupted files
+- **Resource Loading**: Added validation and recovery for failed resource loads
+
+**Best Practices:**
+```gdscript
+# ✅ Comprehensive error handling
+var json = JSON.new()
+var parse_result = json.parse(json_string)
+if parse_result != OK:
+    DebugManager.log_error("JSON parsing failed at line %d: %s" % [json.error_line, json.error_string], "SettingsManager")
+    _load_default_settings()  # Fallback mechanism
+    return
+
+# ❌ Minimal error handling (now improved)
+if json.parse(json_string) != OK:
+    DebugManager.log_error("Error parsing JSON", "SettingsManager")
+    return  # No fallback, system left in undefined state
+```
+
+**Files Improved:**
+- `src/autoloads/SettingsManager.gd`
+
+### 3. Race Conditions & Concurrency
+
+**Issues Fixed:**
+- **Scene Loading**: Protected against concurrent scene changes with state flags
+- **Resource Loading**: Added proper validation and timeout protection
+- **State Corruption**: Prevented state corruption during async operations
+
+**Best Practices:**
+```gdscript
+# ✅ Race condition prevention
+var is_changing_scene: bool = false
+
+func start_game_with_mode(gameplay_mode: String) -> void:
+    if is_changing_scene:
+        DebugManager.log_warn("Scene change already in progress", "GameManager")
+        return
+
+    is_changing_scene = true
+    # ... scene loading logic ...
+    is_changing_scene = false
+
+# ❌ Unprotected concurrent access (now fixed)
+func start_game_with_mode(gameplay_mode: String) -> void:
+    # Multiple calls could interfere with each other
+    get_tree().change_scene_to_packed(packed_scene)
+```
+
+**Files Improved:**
+- `src/autoloads/GameManager.gd`
+
+### 4. Architecture Issues
+
+**Issues Fixed:**
+- **Global Static State**: Eliminated problematic static variables that prevented testing
+- **Instance Isolation**: Replaced with instance-based architecture
+- **Testability**: Enabled proper unit testing with isolated instances
+
+**Best Practices:**
+```gdscript
+# ✅ Instance-based architecture
+func set_active_gem_types(gem_indices: Array) -> void:
+    if not gem_indices or gem_indices.is_empty():
+        DebugManager.log_error("Empty gem indices array", "Tile")
+        return
+    active_gem_types = gem_indices.duplicate()
+
+# ❌ Static global state (now eliminated)
+static var current_gem_pool = [0, 1, 2, 3, 4]
+static func set_active_gem_pool(gem_indices: Array) -> void:
+    current_gem_pool = gem_indices.duplicate()
+```
+
+**Files Improved:**
+- `scenes/game/gameplays/tile.gd`

+
+**Implementation:**
+- Created `DebugMenuBase.gd` with shared functionality
+- Refactored existing classes to extend base class
+- Added input validation and error handling
+
+```gdscript
+# ✅ Unified base class
+class_name DebugMenuBase
+extends Control
+
+# Shared functionality for all debug menus
+func _initialize_spinboxes():
+    # Common spinbox setup code
+
+func _validate_input(value, min_val, max_val):
+    # Input validation logic
+
+# ✅ Derived classes
+extends DebugMenuBase
+
+func _find_target_scene():
+    # Specific implementation for finding target scene
+```
+
+**Files Created/Improved:**
+- `scenes/ui/DebugMenuBase.gd` (new)
+- `scenes/ui/DebugMenu.gd` (refactored)
+- `scenes/game/gameplays/Match3DebugMenu.gd` (refactored)
+
+### 2. Input Validation & Security

+```
+
+**Files Improved:**
+- `scenes/ui/SettingsMenu.gd`
+- `scenes/game/gameplays/match3_gameplay.gd`
+- `src/autoloads/GameManager.gd`
+
+## Development Standards
+
+### Memory Management Rules
+
+1. **Always use `queue_free()`** instead of `free()` for node cleanup
+2. **Wait for frame completion** after queueing nodes for removal
+3. **Clear references before cleanup** to prevent access to freed memory
+4. **Connect signals properly** for dynamically created nodes
+
+### Error Handling Requirements
+
+1. **Provide fallback mechanisms** for all critical failures
+2. **Log detailed error information** with context and recovery actions
+3. **Validate all inputs** before processing
+4. **Handle edge cases** gracefully without crashing
+
+### Architecture Guidelines
+
+1. **Avoid global static state** - use instance-based architecture
+2. **Implement proper encapsulation** with private/protected members
+3. **Use composition over inheritance** where appropriate
+4. **Design for testability** with dependency injection
+
+### Input Validation Standards
+
+1. **Type checking** - verify input types before processing
+2. **Bounds checking** - validate numeric ranges and array indices
+3. **Null checking** - handle null and empty inputs gracefully
+4. **Whitelist validation** - validate against known good values
+
+## Code Quality Metrics
+
+### Before Improvements
+- **Memory Safety**: Multiple potential crash points from improper cleanup
+- **Error Recovery**: Limited error handling with undefined states
+- **Code Duplication**: 90% duplicate code in debug menus

+    var initial_count = get_child_count()
+    create_and_destroy_nodes()
+    await get_tree().process_frame
+    assert(get_child_count() == initial_count)
+```
+
+### Error Handling Testing
+```gdscript
+# Test fallback mechanisms
+func test_settings_fallback():
+    delete_settings_file()
+    var settings = SettingsManager.new()
+    assert(settings.get_setting("master_volume") == 0.5)  # Default value
+```
+
+### Input Validation Testing
+```gdscript
+# Test bounds checking
+func test_volume_validation():
+    var result = settings.set_setting("master_volume", 2.0)  # Invalid range
+    assert(result == false)
+    assert(settings.get_setting("master_volume") != 2.0)
+```

+# UI Components
+
+This document describes the custom UI components available in the Skelly project.
+
+## ValueStepper Component
+
+### Overview
+
+**ValueStepper** is a reusable UI control for stepping through discrete values with left/right arrow navigation. It provides an intuitive interface for selecting from predefined options and is particularly well-suited for game settings menus.
+
+**Location**: `scenes/ui/components/ValueStepper.tscn` and `scenes/ui/components/ValueStepper.gd`
+
+### Why ValueStepper Exists
+
+Godot's built-in controls have limitations for discrete option selection:
+- **OptionButton**: Dropdown popups don't work well with gamepad navigation
+- **SpinBox**: Designed for numeric values, not text options
+- **HSlider**: Better for continuous values, not discrete choices
+
+ValueStepper fills this gap by providing:
+- ✅ **Gamepad-friendly** discrete option selection
+- ✅ **No popup complications** - values displayed inline
+- ✅ **Dual input support** - mouse clicks + keyboard/gamepad
+- ✅ **Clean horizontal layout** with current value always visible
+- ✅ **Perfect for game settings** like language, difficulty, resolution
+
+### Features
+
+- **Multiple Data Sources**: Built-in support for language, resolution, difficulty
+- **Custom Values**: Easy setup with custom arrays of values
+- **Navigation Integration**: Built-in highlighting and input handling
+- **Signal-Based**: Clean event communication with parent scenes
+- **Visual Feedback**: Automatic highlighting and animations
+- **Audio Support**: Integrated click sounds
+- **Flexible Display**: Separate display names and internal values
+
+### Visual Structure
+
+```
+[<] [Current Value] [>]
+```
+
+- **Left Arrow Button** (`<`): Navigate to previous value
+- **Value Display**: Shows current selection (e.g., "English", "Hard", "1920×1080")
+- **Right Arrow Button** (`>`): Navigate to next value
+
+## API Reference
+
+### Signals
+
+```gdscript
+signal value_changed(new_value: String, new_index: int)
+```
+Emitted when the value changes, providing both the new value string and its index.
+
+### Properties
+
+```gdscript
+@export var data_source: String = "language"
+@export var custom_format_function: String = ""
+```
+
+- **data_source**: Determines the data type ("language", "resolution", "difficulty", or "custom")
+- **custom_format_function**: Reserved for future custom formatting (currently unused)
+
+### Key Methods
+
+#### Setup and Configuration
+```gdscript
+func setup_custom_values(custom_values: Array[String], custom_display_names: Array[String] = [])
+```
+Configure the stepper with custom values and optional display names.
+
+#### Value Management
+```gdscript
+func get_current_value() -> String
+func set_current_value(value: String)
+func change_value(direction: int)
+```
+Get, set, or modify the current value programmatically.
+
+#### Navigation Integration
+```gdscript
+func set_highlighted(highlighted: bool)
+func handle_input_action(action: String) -> bool
+func get_control_name() -> String
+```
+Integration methods for navigation systems and visual feedback.
+
+## Usage Examples

+1. **Add to Scene**: Instance `ValueStepper.tscn` in your scene
+2. **Set Data Source**: Configure the `data_source` property
+3. **Connect Signal**: Connect the `value_changed` signal
+
+```gdscript
+# In your scene script
+@onready var language_stepper: ValueStepper = $LanguageStepper
+
+func _ready():
+    language_stepper.value_changed.connect(_on_language_changed)
+
+func _on_language_changed(new_value: String, new_index: int):
+    print("Language changed to: ", new_value)
+```
+
+### Built-in Data Sources
+
+#### Language Selection
+```gdscript
+# Set data_source = "language" in editor or code
+language_stepper.data_source = "language"
+```
+Automatically loads available languages from SettingsManager.
+
+#### Resolution Selection
+```gdscript
+# Set data_source = "resolution"
+resolution_stepper.data_source = "resolution"
+```
+Provides common resolution options with display names.
+
+#### Difficulty Selection
+```gdscript
+# Set data_source = "difficulty"
+difficulty_stepper.data_source = "difficulty"
+```
+Provides difficulty levels: Easy, Normal, Hard, Nightmare.
+
+### Custom Values
+
+```gdscript
+# Setup custom theme selector
+var theme_values = ["light", "dark", "blue", "green"]
+var theme_names = ["Light Theme", "Dark Theme", "Blue Theme", "Green Theme"]
+theme_stepper.setup_custom_values(theme_values, theme_names)
+theme_stepper.data_source = "theme"  # For better logging
+```
+
+### Navigation System Integration
+
+```gdscript
+# In a navigation-enabled menu
+var navigable_controls: Array[Control] = []
+
+func _setup_navigation():
+    navigable_controls.append(volume_slider)
+    navigable_controls.append(language_stepper)  # Add stepper to navigation
+    navigable_controls.append(back_button)
+
+func _update_visual_selection():
+    for i in range(navigable_controls.size()):
+        var control = navigable_controls[i]
+        if control is ValueStepper:
+            control.set_highlighted(i == current_index)
+        else:
+            # Handle other control highlighting
+            pass
+
+func _handle_input(action: String):
+    var current_control = navigable_controls[current_index]
+    if current_control is ValueStepper:
+        if current_control.handle_input_action(action):
+            AudioManager.play_ui_click()
+            return true
+    return false
+```
+
+## Integration Patterns
+
+### Settings Menu Pattern
+See `scenes/ui/SettingsMenu.gd` for a complete example of integrating ValueStepper into a settings menu with full navigation support.
+
+### Multiple Steppers Navigation
+See `examples/ValueStepperExample.gd` for an example showing multiple steppers with keyboard/gamepad navigation.
+
+## Extending ValueStepper
+
+### Adding New Data Sources
+
+1. **Add to `_load_data()` method**:
+```gdscript
+func _load_data():
+    match data_source:
+        "language":
+            _load_language_data()
+        "your_custom_type":
+            _load_your_custom_data()
+        # ... other cases
+```
+
+2. **Implement your loader**:
+```gdscript
+func _load_your_custom_data():
+    values = ["value1", "value2", "value3"]
+    display_names = ["Display 1", "Display 2", "Display 3"]
+    current_index = 0
+```
+
+3. **Add value application logic**:
+```gdscript
+func _apply_value_change(new_value: String, index: int):
+    match data_source:
+        "your_custom_type":
+            # Apply your custom logic here
+            YourManager.set_custom_setting(new_value)
+```
+
+### Custom Formatting
+
+Override `_update_display()` for custom display formatting:
+
+```gdscript
+func _update_display():
+    if data_source == "your_custom_type":
+        # Custom formatting logic
+        value_display.text = "Custom: " + display_names[current_index]
+    else:
+        super._update_display()  # Call parent implementation
+```
+
+## Best Practices
+
+### When to Use ValueStepper
+- ✅ **Discrete options**: Language, difficulty, resolution, theme
+- ✅ **Settings menus**: Any option with predefined choices
+- ✅ **Game configuration**: Graphics quality, control schemes
+- ✅ **Limited options**: 2-10 options work best
+
+### When NOT to Use ValueStepper
+- ❌ **Continuous values**: Use sliders for volume, brightness
+- ❌ **Large lists**: Use ItemList or OptionButton for 20+ items
+- ❌ **Text input**: Use LineEdit for user-entered text
+- ❌ **Numeric input**: Use SpinBox for number entry
+
+### Performance Considerations
+- ValueStepper is lightweight and suitable for multiple instances
+- Data loading happens once in `_ready()`
+- Visual updates are minimal (just text changes)
+
+### Accessibility
+- Visual highlighting provides clear focus indication
+- Audio feedback confirms user actions
+- Keyboard and gamepad support for non-mouse users
+- Consistent navigation patterns
+
+## Common Issues and Solutions
+
+### Stepper Not Responding to Input
+- Ensure `handle_input_action()` is called from parent's `_input()`
+- Check that the stepper has proper focus/highlighting
+- Verify input actions are defined in project input map
+
+### Values Not Saving
+- Override `_apply_value_change()` to handle persistence
+- Connect to `value_changed` signal for custom save logic
+- Ensure SettingsManager or your data manager is configured
+
+### Display Names Not Showing
+- Check that `display_names` array is properly populated
+- Ensure `display_names.size()` matches `values.size()`
+- Verify `_update_display()` is called after data loading
+
