A screen recording of a colorful side-scrolling platformer built from one prompt in an arena chat, where a small hero runs across grassy and pink candy stages collecting coins, hitting question blocks and passing a green pipe.

HOLY SHIT MOMENT with Opus 5.5 😱 I really wanted to play Super Mario Bros Wonder but I don't have a Nintendo Switch.... So I went to @arena with the hop to find an AI that could reproduce the game. And luckily I stumbled upon Opus 5.5 ✨ Have a look at what it did with ONE prompt 😵💫 For those interested I'll share the result of Grok 4.7 in the comments
