It's a horror style escape game!
This is a popular exit inspired game.

``The next thing you know, you've wandered into an underground passage, and you end up wandering around looking for an exit to get out of here...''

There is no game over element!
No more creepy people chasing you!
Please feel safe and look for the exit.
Play with earphones or headphones for a more realistic experience! Please try it!

The game isn't difficult at all, so
How about competing for the clear time when playing laps?
RTA and quick clears are also welcome! ! !

■Rules
There are multiple upward stairs that serve as exits,
If you climb a staircase with only one correct answer and an incorrect answer, you will be pulled back to the underground passage.
Also, the shape of the underpass is random each time.
Explore with a fresh mind every time!

■Tips
There are exit (stair) opening/closing buttons at various locations in the underpass.
By pressing this button, you can close the incorrect exit with a shutter.
However, since there are fewer buttons than incorrect exits, it is not possible to close all incorrect exits. Please be careful!
There is a high probability that the correct exit will be located further away from the starting point.
An exit that is close to the starting point may also be the correct answer, just because the probability is high.
