A downloadable game

During a codebreaker exam, an aspiring but uncertain cryptographer discovers an odd event that opens the door to a conspiracy that involves a friend--the helpful (but stuck in the 80s) Artificial Intelligence, MIA.

This short game was made in a week. You can watch the gameplay video to get the whole story, but I would recommend playing it just the same. Enjoy!
