Crypto Cracker

A substitution cipher is a method of encrypting text by replacing each letter with a different letter or symbol. In this game, we're using a simple Caesar cipher, where each letter is shifted by a fixed number of positions in the alphabet.

For example, with a shift of 3:
A → D, B → E, C → F, ..., X → A, Y → B, Z → C

While simple substitution ciphers like this are easy to break, they form the basis for understanding more complex encryption methods used in modern cryptography.
