After you created a character you begin the first level, "Mail Room" .In this level you are given a task that is shown ate the upper right of the screen and it is telling you tan you need to take all the boxes in the inbox and move them to the outbox
To for fill this first assignment you need to use the 2 commands that are given. At first we use "Inbox" and play the program then we see that our worker leads to the inbox and picks up a box
When we use the command "Outbox" we see how the character takes the box to the outbox and drop the box there
To finish the level we will only need to repeat those steps 3 times and he will take all the boxes, one by one.
