Dupery: A Game of Solo Deduction & Teller's Duty

You’ve just started your first day as a bank teller at Kertasia Bank, thanks to a favor from your distant uncle, the branch manager. But this isn’t just a job, it’s your lifeline. With your mother’s medical bills piling up, every decision at the counter could shape your future in a country run by absurd rules and an even more absurd government.

But counting cash is the least of your worries.

You'll spot forgeries, calm irate customers, and navigate the bizarre, ever-changing regulations of a dysfunctional government. Each interaction tests your patience, your integrity, and your resolve.

As days pass, pressure mounts. Your uncle demands results, but the bank’s policies often clash with what’s right. Will you follow the rules to survive, or take risks for your family’s sake?
