Run! The walls are shrinking! This is about solving puzzles by pushing boxes from collapsing secret room. Accurately plan your steps, avoid deep pits and traps, use polymer and portal wall in the room, and escape from the secret room to avoid being crushed into a puddle of flesh by the walls.

Observe the timing of the wall contractions each turn, precisely plan your steps, avoid falling into traps, make good use of the interactive mechanisms within the levels, push the boxes to open the gates, and escape from the secret chamber before being squeezed into a pulp by the walls!

There are all kinds of interesting traps in the chamber: Signal Pressure Plate, Polymers, Portal Walls, Anchor Crate and Clicker. A variety of challenging level puzzles with rich variations await you to solve!
Welcome to take on the challenge!

You can move freely in the level selection scene. Just collect computing power points through the main challenges to unlock subsequent chapters, but the difficult puzzles in the corners are the real challenges.
Meanwhile, besides solving puzzles, you can also explore virtual exhibits and search for hidden levels in the scene. A large number of Easter eggs are waiting for you to discover them.

300+ levels.
5 themed chapters.
X+ exhibits with black-humor memes.
