Round-based Sokoban & Escape From Danger
The basic gameplay of Shrink Rooms is to solve puzzles by pushing boxes.
Different from other puzzle games, the walls of the level's room will contract inward at the end of each round. You must accurately plan the number of steps for pushing boxes to escape from the secret room, so as to avoid being crushed into a puddle of flesh by the walls.
Massive Mechanisms & Creative Combinations
There are various interesting mechanisms in the shrink rooms. The characteristics of different mechanisms are combined to generate many puzzles with rich variations and high difficulty. Welcome to challenge!

Flexible Selection & Free Exploration
You can move freely in the selection scene. You can choose easier puzzles to continue the game, or try to solve all difficult puzzles.
At the same time, in addition to solving puzzles, you can also explore and collect virtual exhibits and find hidden levels in the scene to explore different fun.

Game features
200+ levels.
4 themed chapters.
X+ exhibits with unique drawings and descriptions.

[/*]Completed refactoring of underlying code, significantly reducing bugs in complex levels involving Polymers, Portals, etc. ([u]If you encounter any, please give feedback to Mat-Rixs Discord[/u]).
[/*]Completed localization proofreading for the Japanese version.
[/*]
Level Adjustments:
Removed some levels that were inconsistent with the mechanics of preceding and following levels and had jarring difficulty jumps, including: 1-13, 1-38, 1-40, etc.
[/*]Fixed unintended solutions for some levels, including: 1-18, 3-45, C-07, 4-36, E-05, E-16, etc.
[/*]Redesigned levels A-05, A-06, and B-04 while preserving their core reasoning logic.

[/*]Adjusted the positions of portals around level 3-65 in the chapter 3 level selection map.
[/*]Added 1 new side level at the end of the C-07 level sequence.
[/*]
Bugfixes & Optimizations:
The game now correctly handles multi-polymer consumption issues when passing through portals under specific circumstances.
[/*]Fixed the error where players couldnt move when a pair of portals were in adjacent corners.
[/*]Fixed some polymer breakage errors in complex structures.
[/*]Fixed the issue where the game incorrectly played a death animation if the player was in a pit after undoing an action.
[/*]Fixed undo errors involving multi-polymer consumption that affects structures.
[/*]Fixed the breakage error when boxes are stuck on inactive portals.
[/*]Fixed the error where wires turn green after pressure plates connected to NOT gates are destroyed.
[/*]Fixed logic errors in complex scenarios involving portals, multi-polymer consumption, and polymer breakage.
[/*]Fixed the issue where \"self-sticking\" was incorrectly triggered.
[/*]Fixed the error where pushing boxes triggers polymer consumption when portals and multiple polymers are adjacent.
[/*]Fixed the error where linked structures are incorrectly destroyed when walls push players and box-sticking structures.
[/*]Fixed polymer breakage logic errors when complex structures move due to multi-polymer consumption.
[/*]Fixed polymer breakage logic errors when players stick to complex structures and move toward walls.
[/*]Fixed logic errors when players stick to complex structures and move toward adjacent corner portals.
[/*]Fixed logic errors when structures move toward portals due to multi-polymer consumption.
[/*]Fixed incorrect polymer structure breakage when boxes are crushed.
[/*]Fixed the error where players overlap with walls if players and boxes are not pushed correctly during the same wall movement.
[/*]Fixed the missing sound effect when walls are blocked by anchor boxes.
