Overview
Musou Yuugi (夢想遊戯, Dream Play) is a Yume Nikki fangame made by Atami (熱海). It stars Shirayuki (白雪), a girl who refuses to leave her room. The game seems to have a theme of Japanese folklore/theatre.

You can also buy some ornaments for your dream room from the market sellers in certain worlds.
