Quotidian Shift is a puzzle game based on a monthly calendar. It was created at TOJam 2012 (the annual Toronto Game Jam).
Designed as a simple, yet challenging puzzle game, Quotidian Shift requires the player to shuffle dates on a calendar as the everyman Joe Salaryman lives through his daily life.
The goal of the game is to ensure that predicted "end of the world" events do not happen by keeping Joe from living through those days.
The player and Joe each take turns, the player can shuffle dates on the calendar by sliding a row or column of dates and Joe lives through his day and wakes up on the next adjacent day on the calendar.
As the days get mixed up, the player must pay close attention, as a time paradox will be created if he lives through the same day twice.
Gameplay videos will be uploaded soon!
You can read a post-mortem, outlining the successes and failings of the project, at my blog. I also blogged the progress of the game throughout TOJam.
