You, trapped in an unknown facility, and your only alternative for survival
it's the obvious paths with solving puzzles. Nothing will make it easier.

The path is narrow and each puzzle gets complicated, or adapts to a situation.
Repeated changes, tests performed, and a totally non-normal universe.

The world is starting to be narrow and it is necessary to move forward.


-- Water Tunnel
When you get halfway there, the properties of a water have gone
fully altered, called "Water Tunnel", allowing you to breathe,
swim more easily, and feel like a being there.

The tests are now changed for this property.


-- above midway
It got to the point where the installation was less preserved,
destroyed and with unplanned obstacles.

with increased difficulty.


- No purpose.
From a path to the exit, your goal became to flee the shadows
they have started to consume and it is necessary to flee.
Try your best to survive this era.
