Hi, the package is not charged in all. you have to upload the files individually for what you need them.
For example:
-to insert a sprite: Click the right mouse button on the white part (background) and select "insert a new object"
- Select "Sprite icon" and Press the button "insert"
- Click with the left mouse button anywhere in the background
a blue box will appear, and you must press the "load file from file" icon and find the sprite on your pc in the folder you downloaded the package. and that's it.
