Crack the Code Before the Sun Sets — My June Solstice Game Jam Entry

June Solstice Game Jam Submission

This is a submission for the June Solstice Game Jam

What I Built

Solstice Cipher: Enigma of the Longest Day is a browser-based puzzle game built around the Caesar cipher — the same substitution cipher technique used in ancient cryptography. On the theme of the June Solstice, I tied the longest day of the year to an Enigma Machine-inspired challenge: decode encrypted messages before time runs out, with the difficulty scaling as the sun climbs higher.

The game features a real-time animated sky that shifts through dawn, noon, and dusk to reflect the solstice theme. Players are given a cipher shift key and must decode encrypted phrases by working through the Caesar cipher manually or by reasoning out the pattern — no brute-force tools allowed in-game.
