ReiLua-Enhanced Game Template
Entry point for your game

This template includes:
- Classic OOP library (class system)
- GameState management (scene/state switching)
- Animation system (sprite sheet animations)
- Example menu and game states

Quick Start:
1. Edit states/menu.lua for your main menu
2. Edit states/game.lua for your gameplay
3. Add assets to assets/ folder
4. Run with: ReiLua.exe --log --no-logo (for development)

For production build:
1. Copy all files to ReiLua-Enhanced/build/
2. Run: scripts\build_release.bat

  -- Disable ESC key from closing the window (so we can use it for pause menu)

  -- Initialize audio

  -- Register GameState callbacks

  -- GameState will handle drawing for current state

-- Optional: Window configuration
-- Call this before InitWindow if you need custom window setup
function RL.config()
  -- Example: Set custom window size before init
  -- RL.SetConfigFlags(RL.FLAG_WINDOW_RESIZABLE)
end

-- Optional: Handle window/input events
function RL.event(event)
  -- Handle events here if needed
  -- Example: event.type == RL.GLFW_KEY_EVENT
