Whose Hellos Are These, Anyway?

Step into a witty world where you're a socially awkward 'Hello-Log' artist, tasked with deciphering a series of bizarre greetings left behind in a deserted art gallery. Each greeting you decode leads to a different character, all of whom are eccentric in their own right. Interact with an array of quirky figures, blend humor with determination, and use your best deduction skills to unveil the true identities and intentions behind the absurd hellos. Will you become the ultimate Hello-Log master or will you find yourself lost in a pandemonium of pleasantries?
