In 'Hello, World?', you play as Alex, a retro video game programmer who mysteriously receives a message from an old video game that was thought to be defunct. The game glitches out, pulling Alex into a digital universe where they confront characters from their past, including friends, foes, and forgotten dreams. As Alex navigates this surreal landscape, they must solve riddles and choose paths that reflect their choices in real life, ultimately revealing the psychological impact of their everyday decisions. With each decision, players can influence the outcome, leading to multiple endings that delve into the themes of identity, regret, and the pursuit of purpose—all while avoiding the satire-filled commentary of the characters who exist in the game.
