Opus 5.5 spent 47 hours and $2,550 building a game so I can DESTROY it! I wanted to push Claude to the limit (including weekly usage limit🤣). Most AI games are pretty pictures; I want some real action🔥 So it built Kaiju Tamagotchi: hatch as a tiny lizard, then eat and smash your way through New York until you're a 100 m titan. Every building breaks. I expected way less. It took 47 hours, used fewer tokens than my last game (5B against almost 8B), and the pipelines were smarter this time.
