This is one of the few true 3D games for the PC-98. It's ported from the PC/AT and from its original english. You play a detective (male or female) trapped in a house full of horrors, and try to escape.
Anex doesn't like this game, so I suggest T98-Next. You'll need to up the emulator system settings to 66 Mhz for the game to be playable in a smooth fashion.
