3レーンのエンドレスランナーを3つのAIモデルで比較

Build a Subway Surfers-style endless runner that plays in a phone-sized portrait window in the browser. Use a self-contained HTML page with a pseudo-3D three-lane track that runs toward the horizon, a pink-and-purple city skyline, green verges and a small runner character. Let the player switch lanes and jump with swipe or arrow keys. Spawn coins in lines, low barriers and oncoming trains, and speed the game up over time. Show a score and a coin counter at the top, a pause button, and a game-over card with the final score and a bright Run Again button. Keep the interface clean and rounded, with smooth animation and clear collision feedback. Expect to refine it with at least one follow-up message about visuals and feel. Done means a run starts instantly, controls respond well and restarting is one click.
