You are an expert game developer. Build a COMPLETE, fully playable browser game: a road-and-river crossing action game, as a single self-contained HTML file using vanilla JavaScript and the HTML5 Canvas API. No external libraries, no external assets, no network. Required features: 1. Intro / start menu screen with the title, brief instructions, and a Start control. 2. Core road-crossing gameplay: a small amphibian the player moves with the arrow keys; a road section with moving vehicles to dodge (collision = lose a life) and a river section with logs/ turtles the frog must ride (falling in the water = lose a life); reach the goal row to score. 3. Two distinct levels with increasing difficulty (faster / denser traffic on level 2); the game advances from level 1 to level 2 after the first is cleared. 4. Game states: lives and score HUD, a game-over screen, and a game-completion / victory screen shown after both levels are finished, with a way to restart. 5. A smooth game loop using requestAnimationFrame, keyboard controls, and collision detection. Output the ENTIRE game as ONE html code block (HTML + CSS + JS inline) that runs by saving it as a single .html file and opening it in a browser.
