"Gameplay Instructions
This is a puzzle elimination game that combines the shapes of Tetris with the sliding mechanics of Klotski (Huarong Dao). The core objective is to eliminate all shapes by sliding the blocks on the board into their matching colored exits within the time limit.

Core Gameplay & Rules
Primary Goal: Eliminate all differently colored Tetris-shaped blocks by sliding each complete shape into the exit that matches its color before the timer runs out.

Movement Rules:

The player can only slide one complete ""Tetris"" shape as a whole per move.

Blocks cannot be rotated, flipped, or jumped over. They must slide within the empty spaces on the board, similar to Klotski.

The purpose of movement is to clear a path for key blocks to reach their exit.

Elimination Condition: A shape is only eliminated when all blocks of that complete shape have entered the exit zone that is exactly the same color.

Win/Loss Conditions:

Win: Eliminate all blocks before the countdown timer reaches zero.

Loss: The timer reaches zero while there are still blocks remaining on the board."
