Design Statement My external goal is to develop a gameplay mechanic that could possibly be applied to a multi-player Facebook game at some point in the future. Time as a game mechanic within the puzzle genre seems full of potential and is well complimented by the spirit and style of steampunk.
General Description The object is to exit the area, and the player has three phases to work with: past, present and future. Players are given time-warped pieces found in the room, which they can play and use only in specific phases (indicated on the pieces.) For instance, the player is given a door piece they can only play in the past and only interact with in the future.
Audience and Context The target audience is the casual puzzle game crowd, most notably fans of the steampunk genre. The context it is to be played in is (currently) single-player computer gaming sessions.
Motivation My own particular motivation is to explore the game mechanic of time in a puzzle setting, and also reaquaint myself with programming concepts. Externally, players should feel compelled by the story elements and appealing style of the game, but also intrigued by the prospect of solving puzzles based on the relationship between objects in the field of three phases of time.
Genre Puzzle/platformer
Story You are a brilliant female inventor preparing to launch your amazing new time machine to save the world from a fatal mistake that caused the eruption of a worldwide conflict. However, something went terribly wrong with your maiden voyage. As the smoke clears, you realize that you’re neither here nor there. In fact, you seem to have become lodged somewhere in an off-branch of the time stream, with only the smallest components of your time device in your possession. Using your limited time-altering functionality and what time-warped items you can find around you, escape this strange place!
Game Mechanics Overview The protagonist possesses a limited flux alternator which causes the area around her to be

pushed into a one of three phases: past, present, or future. However, due to the accident, the device has limited capacity, which she will only be able to rebuild over time. The quantum energy meter indicates how many phase adjustments may be made in the current level (bars.) Any items picked up are stored in the inventory by default. Items may be played in the level according to their specific rules. For instance, certain items may only be played in the past and interacted with in the future, door knobs may only be played on door handles, certain keys pair to certain types of locks, etc. Item requirements may be viewed at any time by hovering the item.

Use Jilted Door. Story Snippet: A torn fragment of your notebook flickers unstably on the floor, a composition your don’t remember ever writing, but that mysteriously details your current situation. “The time machine isn’t here with me… where ever here is. From what my log readings indicate, some type of interference caused the generator to sputter, which in turn scrambled the parameters I had entered. I’m stranded somewhere outside of reality and existing time, but everything is still somehow connected. This looks like the federation’s library. I was trying to get to the capital…”
