This is a classic 2048 game implemented through bitwise operations. It consists of only one file (.bash), with zero dependencies and less than 200 lines of code. Different from the common way of simulating the game board with a two-dimensional array, this project cleverly uses bitwise operations to manage the game state and logic. The entire 4x4 game board is compressed and stored in a 64-bit integer, and all movements, merges and generations are achieved through bit operations.
