<Hael> is a purely vibe-coded web game for which I proposed the design, with assistance from a design-oriented Agent and a code-oriented Agent, under HTML+CSS technical framework. In the game, players take on the role of an active social media blogger on the mobile social platform <Hael>. By reading various posts and private messages, they piece together clues, write articles to gain followers, and ultimately uncover the mystery surrounding their own origins. MainMenu Private
