In 'Whose Hello?', players take on the role of a quirky, down-on-their-luck private investigator who receives a mysterious phone call each day, filled with cryptic 'hellos' that lead to bizarre adventures across the city. Each response unlocks unusual side quests that range from finding missing pet lizards to unraveling the case of the Vanishing Vending Machine. As you interact with a colorful cast of eccentric characters and solve outlandish puzzles, you’ll uncover a larger conspiracy that connects the random phone calls. But there’s a twist: your choices shape not only the outcome of individual quests but also the nature of your mysterious caller, leaving you questioning whether they are friend or foe.
