In 'Who Said Hello?', you find yourself embroiled in an eccentric mystery set in a mundane corporate office. Players assume the role of a recently hired HR intern who discovers a series of cryptic messages left on sticky notes throughout the office. These notes, each signed with a different pseudonym, lead to an underground society of quirky employees who communicate through obscure humor and riddles. As you unravel the connections and learn the secrets behind the seemingly mundane offices, the clock is ticking: uncover the identity of the message author before the next corporate meeting, or risk being permanently lost in absurd office politics. The choices you make will shape alliances, expose hidden truths, and determine whether the office will embrace its newfound freedom or continue to work in silence.
