An entertainment smartphone application designed to change the currency used throughout the world. 【Main Functions】 The primary function is to change the world's current currency (banknotes and coins) into something else. These are broadly divided into two categories: Objects and Actions. 1. Objects: This setting establishes a specific item as currency, similar to traditional banknotes, enabling a barter-style system. Examples include stones or seashells. 2. Actions: Unlike physical objects, this setting establishes a specific behavior as the currency (price). Transactions are completed by performing the designated action under specified conditions. Examples include playing Rock-Paper-Scissors or dancing. Once changed, the original currency ceases to function entirely, but the user can revert to the original system with a single touch once they are finished playing. When the currency is changed, a common-sense alteration is applied to everyone except the app user, making the new system seem perfectly natural and safe. ※ The currency change will forcibly end 24 hours after the app is closed.
