App Profile: Sokoban Master Game

The most classic casual puzzle game in history.
Boxes can only be pushed, not pulled. Only one box can be pushed at a time. Be careful not to push the case into a dead end, or you won't be able to push it any more.
The rules of the Sokoban game are simple, but different levels of difficulty require different levels of brain power. It requires a little skill but is not complicated, and it is playable and interesting.
The purpose of this game is to push all the boxes in a crowded warehouse to the target position with the least number of steps.
