Vibe Sail: A Week-Long Game Dev Success Story Powered by AI

Nicola Manzini built a multiplayer online sailing simulator, Vibe Sail, in just one week using AI-assisted coding tools Cursor and Replit. Starting with a simple concept—one boat, one island, a vast ocean—he progressively added physics, camera systems, wind controls, and more, even refining game physics with insights from the r/sailing subreddit. The game quickly gained traction, boosted by endorsements from prominent figures like Levels, leading to in-game advertising revenue. This case study showcases the power of AI-assisted development and highlights the developer's strong understanding of game mechanics and coding.
