A "vibecoder" created a *Marvel's Spider-Man* clone using Opus 5.5; it runs directly in the browser. Features include web-swinging, wall-running, and a simulated New York City complete with traffic and pedestrians. The city and models were created using Blender. 🤯 The model's capabilities have improved significantly compared to Fable 5; the demos now look much more like actual prototypes. The creator has released the full code here https://github.com/xikhar/spiderbench, so you can try recreating it yourself.
