Shrink Rooms

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!
