+# Common Issues and Solutions
+
+## ESC Key Closes the Game
+
+### Problem
+By default, RayLib sets ESC as the exit key. When you press ESC, `WindowShouldClose()` returns true and the game closes immediately, even if you want to use ESC for pause menus or other game functionality.
+
+### Solution
+Disable the default ESC exit key behavior by calling `RL.SetExitKey(0)` in your `RL.init()` function:
+
+```lua
+function RL.init()
+  -- Window setup
+  RL.SetWindowTitle("My Game")
+  
+  -- Disable ESC key from closing the window
+  RL.SetExitKey(0)  -- 0 = KEY_NULL (no exit key)
+  
+  -- OR set a different exit key
+  -- RL.SetExitKey(RL.KEY_F12)  -- Use F12 instead
+  
+  -- Rest of initialization...
+end
+```
+
+### Options
+
+**Option 1: No Exit Key (Recommended for Games)**
+```lua
+RL.SetExitKey(0)  -- Disable exit key completely
+```
+Now ESC (and any key) won't close the game. Handle exit through:
+- Menu option (File → Exit)
+- Alt+F4 (Windows default)
+- Close window button (X)
+
+**Option 2: Different Exit Key**
+```lua
+RL.SetExitKey(RL.KEY_F12)  -- Use F12 to exit
+```
+Now only F12 will close the game, ESC is free for pause menus.
+
+**Option 3: Custom Exit Handling**
+```lua
+-- In RL.update()
+if RL.IsKeyPressed(RL.KEY_ESCAPE) then
+  -- Show pause menu or confirmation dialog
+  GameState.push(pauseMenu)
+end
+
+if RL.IsKeyPressed(RL.KEY_F10) then
+  -- Exit game
+  RL.CloseWindow()
+end
+```
+
+### Technical Details
+
+**What happens by default:**
+1. RayLib sets ESC as the default exit key
+2. When ESC is pressed, `WindowShouldClose()` returns true
+3. Main loop in `src/main.c` checks this and exits
+
+**After calling `RL.SetExitKey(0)`:**
+1. No key triggers `WindowShouldClose()`
+2. ESC is now available for your game logic
+3. You control when the game exits
+
+### Example: Pause Menu with ESC
+
+```lua
+-- In your game state:
+function GameState:update(dt)
+  -- Pause with ESC
+  if RL.IsKeyPressed(RL.KEY_ESCAPE) then
+    if self.paused then
+      self.paused = false
+    else
+      self.paused = true
+    end
+  end
+  
+  if not self.paused then
+    -- Update game logic
+  end
+end
+```
+
+### Template Fix
+
+The template's `main.lua` has been updated with:
+```lua
+RL.SetExitKey(0)  -- Disable ESC exit key
+```
+
+This allows the game state to use ESC for pause functionality without closing the game.
+
+### Related Functions
+
+- `RL.SetExitKey(key)` - Set which key exits the game
+- `RL.WindowShouldClose()` - Check if game should close
+- `RL.CloseWindow()` - Manually close the window
+- `RL.IsKeyPressed(key)` - Check if key was pressed this frame
+
+### Development Tip
+
+During development, you might want quick exit. Consider:
+```lua
+function RL.init()
+  RL.SetExitKey(0)  -- Disable ESC
+  
+  -- But add debug exit key
+  if DEBUG_MODE then
+    RL.SetExitKey(RL.KEY_F12)
+  end
+end
+```
+
+Or handle it in update:
+```lua
+function RL.update(dt)
+  -- Debug: Quick exit with Shift+ESC
+  if RL.IsKeyDown(RL.KEY_LEFT_SHIFT) and RL.IsKeyPressed(RL.KEY_ESCAPE) then
+    RL.CloseWindow()
+  end
+end
+```
+
+## Other Common Issues
+
+### Window Closes When X Button Clicked
+This is normal behavior. If you want to show a confirmation dialog:
+```lua
+function RL.update(dt)
+  if RL.WindowShouldClose() then
+    -- Show "Are you sure?" dialog
+    -- If player cancels, need to prevent close somehow
+  end
+end
+```
+Note: Preventing X button close is tricky with RayLib's current API.
+
+### Alt+F4 Closes Game
+This is OS-level behavior and cannot be easily disabled. It's recommended to save game state frequently.
