Please create an instant-play web puzzle mini-level (single-file HTML) with 2.5D visuals. The player controls a caped character to traverse obstacles and solve puzzles to progress. The cape should exhibit noticeable physical dynamics (similar to cloth affected by gravity, inertia, and wind), naturally swaying with the character’s movement. Use the mouse wheel to adjust the camera’s zoom or height for easier viewing. The interface should include a fixed score panel displaying the current level’s score/progress. The background should feature a depth-of-field effect: distant elements slightly blurred, near elements sharp. Implement this directly using the Canvas 2D context, minimizing external libraries; a single HTML file is sufficient.
