Stack Boxの旧いバージョンをダウンロードすることが可能
箱をスタック！
Stack the boxes up!
You can stack the boxes by tapping the screen.
Be careful not to break the stack down. The stack would crumble away, if the boxes are put on the wrong spot or stacked too much on one side.
Try to load the boxes on the delivery truck as many s you can.
The more you load, the higher you feel!
Good luck~!
