Avia Cipher

The world is on edge, and vital intelligence flows unseen through the airwaves. As the pilot of a lone reconnaissance aircraft, you are tasked with a dangerous mission: intercept enemy radio transmissions high above the clouds and crack their hidden messages before they disappear. Every signal could carry a secret that changes the course of events - but time and fuel are limited, and mistakes are costly. Only sharp thinking and quick action will keep your mission alive.

Gameplay Features:
Radio Frequency Tuning - Adjust the controls to lock onto the right frequency and begin decoding.
Encrypted Words - Each transmission is scrambled. Shift the letters until the correct word appears.
Missing Letters - Some words arrive incomplete. Select the right letters from the options to restore the message.
Race Against Time - Solve everything before your plane runs out of fuel.
Unique Attempts - Each level selects words at random, so every session feels different.

Progression:
21 Levels - Unlock new levels step by step as you advance.
Stars System - Earn up to 3 stars per level based on your performance.
Cryptography Facts - Collect fascinating facts about real-world cryptography. Each one unlocks when you reach a specific number of stars.
Rising Challenge - Levels grow tougher with longer words and less fuel (shorter time limits).

Test your logic, sharpen your mind, and uncover cryptographic secrets hidden in the skies.
