Gameplay specificationfinal

  1. 1. Lost Pigeon Studios presents fenestraCore Vision An old man tries to take his own life, but finds himself unable to. He discovers thathe has the power to travel between two worlds whenever he dies. The player must usethis power to guide the man through puzzles, reaching a door to exit each level. The twoworlds travelled by the man are a dark, modern city and a bright, vibrant outdoor settingfrom long ago.Design Philosophy The selling points of the game are the abstract puzzle solving mechanic and thereversal of the traditional death-avoidance paradigm. Players must be able to work withboth instances of the world and utilize the objects and layouts of both to get to the doorand continue the game. Regardless of how far behind we get in our game development,we cannot cut out the fundamental element of switching between worlds by dying. If wedo become short on time, we will drop some of our more ambitious mechanics such asgiving the player a vial of poison to kill themselves at will.Objectives The main goal of the game is to beat the levels by unlocking doors or navigatingobstacles using both worlds to get to the end. This is motivated by the characterdevelopment of the protagonist. The thoughts and memories of the protagonist arerevealed as the player progresses, so the player is motivated to solve each puzzle in orderto hear the next part of the story.
  2. 2. ChallengesThe challenge of each level is simply to move the protagonist through the exit door. Theexit will usually be inaccessible in some way, so the player must figure out what tasks needto be accomplished to reach the exit. The player may be challenged with some of thefollowing mechanics:Choice of Death - The puzzles are designed such that the player must die in some wayto reach the end of the level. The principle challenge is for the player to decide whenand where they need to die in order to solve the puzzle.Buttons - The presence of a weighted object will activate the button, opening a door orotherwise altering the level state.Keys - Doors may be locked and require a key to pass through. The key may be in alocation that requires the player to die and pass through the other world, or may exist inboth worlds and need to be carried through with the player.Switches - Players can toggle switches between two states, which changes thebehavior of the object(s) that the switch is connected to. Players may have to activateswitches in specific orders or at specific times to solve a puzzle.Timing Challenges - Players may have to synchronize their death with specific events inone world in order to open a path to the exit.
