This is an escape game. The goal is to get out to the ground.
Click any places in the screen and you'll find hidden items or riddles.
When you feel your PC is too slow in action, pls try the following.
Move a mouse cursor to any point around a right-below area during your play.
Then, "QUALITY" will be appeared in the display.
Click it, and you can change the picture quality of your PC screen.
It is NOT an absolute condition to be able to listen sounds during your play, but it would be an advantage for you to listen sounds at some points.
When you get an item, it will be indicated on the right in the screen.
Click once: selected (back-ground color will be changed)
Click once again: canceled
You can see the item description, with "item info" button, when you select the item.
You can't operate switches or other items when you have selected Item.
You might lose your life, I mean a game over, if you read riddles wrongly.
When you lost your life, you can restart this game, from just before the point when you lost your life, only two times.
I'm so pleased if you could send me your impressions or opinion by mail.
Although I wouldn't be able to reply to you as I'm not good at English. (My friend translated these writings)
