Prompt 3: The game is start with a side-view to show a indoor environment. In this way, the player is naturally limited by the floor, the roof, and the wall. Therefore. the player knows what they could do is talking to the only highlighted character in this page -- the person. Then, go out though the door to the outside world. The other pages are top view, while the road represent as a connection to another scene. Although, it is only one page, the transaction between is page and other place is natural. As we might experience in other games, this page is like a interaction which player can choose of which road to go. This process is like leave a little blank, allowing players to make up the process to go on this road, and then slowly get out of the city, went to the forest, the sea, etc. This processing reduces the abruptness of scene transitions. Besides, almost all the page has a frame made by lines to show the area players could go. Due to Bitsy limit of transition door size, the dotted line in the middle of the road is used as a hint for it. In the road page, there are three open ways without boundary which leads the player. After easily notice that, players will not want to miss either one of them. Players are free to go to more than two directions in this game, so I think it can be considered to be a open format construction.
