Nazo no Mascarade

The game is almost entirely in Japanese, which is quite depressing. Even more frustrating is the fact that you can't get anywhere without understanding the inscriptions. After telling the backstory (in Japanese), you start wandering around the house. On the house plan, you point to a room and immediately get there. (It is to the credit of this game that the plan correctly depicts doors, stairs, etc.). Then the Japanese speech follows again, you intuitively decide what to do, and.... you repeat the whole thing from the beginning, only with another room.
