Much like early console and arcade games, whose limited memory required programmers to break up large environments into chunks that were displayed one screen at a time, Bitsy allows users to create games with multiple rooms that are connected to one another using special tiles called exits. Exits can transport the player to a new room, return them to a previous room, or trigger a game ending. Furthermore, in addition to moving a player across space, they can also function in the way that a film editor might use a cut to signal a transition in time. Using these features, players can creatively stitch a world together one screen at a time.
