Slip 'n' Push Out

It is a game that pushes out all the red boxes on the Ice. Operate the white box. Can move up, down, left, and right, but cannot stop until hit another box. So can only move in the direction of the box. It will stop when it hits the box. The panel that hits is pushed out in the same direction as it is. If it hits another box, the original box will stop there and the box that hits will be pushed out. Use that movement to push the red box out of the ice. The game is finish, when all the red boxes are out of bounds. The game is over, if fail to move and cannot move in any direction. The level goes up depending on the speed of clearing. As the level goes up, the number of boxes increases and the stage becomes complicated. Can "Undo" and "Retry" as many times as like. Clear all 10 stages, the total score will be registered on the leaderboard of the game center.
