Our take on CD-ROM

Rather than using a conventional level sequence, the game frames progression as opening a series of themed CDs. Each stage depends on finding an 8-digit password, while the puzzles focus on concealed information, coded text, images, and embedded programs.

What is CD-ROM?

CD-ROM is a puzzle game structured around 10 themed virtual CDs, each containing challenges that lead to an 8-digit password for accessing the next disc.

Progress involves decoding text, examining images, locating hidden messages, using hints from mini-games, and operating programs found within the CDs. The puzzles draw on cryptography and steganography, with information concealed in different types of data. The game includes mini-games, pixel art graphics, and Steam achievements. Completing the sequence requires finding one password for each of the 10 CDs.
