The game is presently accessible for Microsoft Windows on GamesKnit. Until Dawn is designed to be played multiple times, as players cannot see all content with a single playthrough. Each playthrough lasts about nine hours in length and the game mechanics utilize an in-game system called the “Butterfly Effect” in which any choice of action by the player may cause unforeseen consequences later on.

For example, locating a weapon in an earlier chapter may allow the player to pick it up down the line when a chase scene leads back to the same room.
