+## Project Improvements and Best Practices
+
+### Performance Optimizations
+
+The codebase includes several performance optimizations:
+
+1. **Release Build Configuration**
+   - Minification enabled to reduce APK size
+   - Resource shrinking to remove unused resources
+   - ProGuard rules to optimize while preserving critical classes
+
+2. **Memory Management**
+   - Proper lifecycle handling to prevent memory leaks
+   - Resource cleanup through `releaseResources()` methods
+   - Efficient bitmap handling with reuse when possible
+
+3. **Rendering Efficiency**
+   - Custom view invalidation limited to areas that need updating
+   - Hardware acceleration for canvas operations
+   - Bitmap caching for frequently used graphics
+
+### Code Organization
+
+The codebase follows good architecture practices:
+
+1. **Package Structure**
+   - `model`: Data classes and game logic
+   - `game`: Core gameplay implementation
+   - `ui`: User interface components
+   - `audio`: Sound and music management
+   - `accessibility`: Accessibility helpers
+
+2. **Responsibility Separation**
+   - `GameLifecycleManager`: Handles lifecycle events
+   - `GameUIManager`: Manages UI state and updates
+   - `GameAccessibilityHelper`: Improves accessibility features
+   - `GamepadController`: Manages gamepad input
+
+### Google Play Compliance
+
+The app meets Google Play standards:
+
+1. **Manifest Configuration**
+   - Proper permissions declaration
+   - Screen orientation handling
+   - Full backup rules for user data
+
+2. **Accessibility Support**
+   - Content descriptions for UI elements
+   - Color contrast considerations
+   - Screen reader compatibility
+
+3. **Shortcuts and Deep Links**
+   - App shortcuts for quick actions
+   - Proper intent handling
+
+### Usage Examples
+
+#### Lifecycle Management
+
+```kotlin
+// In your activity
+private lateinit var lifecycleManager: GameLifecycleManager
+
+override fun onCreate(savedInstanceState: Bundle?) {
+    super.onCreate(savedInstanceState)
+    lifecycleManager = GameLifecycleManager(this)
+}
+
+override fun onPause() {
+    super.onPause()
+    lifecycleManager.onPause(gameView, gameMusic, statsManager, highScoreManager)
+}
+
+override fun onResume() {
+    super.onResume()
+    lifecycleManager.onResume(gameView, gameMusic, isMusicEnabled)
+}
+
+override fun onDestroy() {
+    lifecycleManager.onDestroy(gameView, gameMusic, statsManager, highScoreManager)
+    super.onDestroy()
+}
+```
+
+#### Accessibility Implementation
+
+```kotlin
+// In your activity
+private lateinit var accessibilityHelper: GameAccessibilityHelper
+
+override fun onCreate(savedInstanceState: Bundle?) {
+    super.onCreate(savedInstanceState)
+    accessibilityHelper = GameAccessibilityHelper(this)
+    
+    // Setup accessibility descriptions for controls
+    accessibilityHelper.setupAccessibilityDescriptions(
+        leftButton, rightButton, rotateButton, dropButton, 
+        holdButton, pauseButton, gameView, holdPieceView, nextPieceView
+    )
+}
+
+// When level changes
+private fun onLevelUp(newLevel: Int) {
+    accessibilityHelper.announceLevelUp(gameView, newLevel)
+}
+
+// When game ends
+private fun onGameOver(score: Long) {
+    accessibilityHelper.announceGameOver(gameView, score)
+}
+```
