Bletchley's Longest Day: a wartime cipher escape game for the June Solstice Game Jam
Short summary
A browser-based cipher escape game set in fictional Bletchley Park uses Google Gemini for question-specific AI hints that cost time/score. Players solve 15 escalating puzzles across five rooms combining classic ciphers, morse code, and anagrams under a solstice countdown timer. Gemini serves as a limited hint system (penalized, guest-excluded) rather than answer button, making AI part of the game economy.
- •Game jam submission combining classic ciphers with Gemini AI hints penalized by time and score
- •Gemini integrated as gameplay mechanic—question-specific nudges unavailable to unauthenticated players
- •Technical stack: Node server, Supabase auth+leaderboards, Render hosting, hand-built HTML/CSS/JS frontend
Generated with AI, which can make mistakes.
