Sure thing, puzzle‑lover! Think of the level as a cryptic riddle that lives in the scenery. Hide a subtle pattern in the lighting, a set of symbols in the wall textures, or a rhythm in the ambient music—any element that feels natural but has a second life as code. Layer clues so that one discovery unlocks another, and give players a taste of the payoff early to keep the excitement ticking. Make the cipher feel earned, not forced, and let the world itself be the cryptographer.
