Of course, the more powerful the warehouse worker is, the better, preferably as powerful as an elephant ... Hey? The owner really hired an elephant to be a warehouse worker yay! The arrow keys control the elephant to push the cargo, which is of course a breeze for a powerful elephant! However, the trouble is that the warehouse has many dead ends, although it is easy to push, but some places can not be pulled out once stuck, so you can think well before pushing the goods, as long as all the goods are pushed to the place with M marking, you can clock out of work!
