Anxiety has become one of the common problems in society in recent years. As an emerging interactive medium, games can create a first-hand experience for players. Therefore, it is possible to guide the player through behavioral experiments implemented with the game. But in order to reduce the direct damage to the player and make the problem more obvious, metaphorical game is one of the good choices.   In order to design and make such a metaphorical game, I firstly need to collect anxiety triggers and game design related theories into an initial design framework. These theories mainly include metaphorical game, experiential game model and reflection game design. After two iterations of game design core development, I'll be doing demos and interviews with several players. After that, I will summarize these data into several themes. These themes will extend the original design framework, which will also serve as an outcome of this paper. The two most prominent points in the expansion are beat chart and reward.
