You see two (storage) rooms side by side. (Players are also supposed to sit side by side on the same side of the screen?)
Stuff falls from the sky (or appears in the center/appears somehow). You have to select some yourself, while others have to be kicked/thrown/passed to the other side.
Or maybe you just have two “robot arms” and two buttons to press.
- One of them pushes sideways to the other side (to kick packages to the other player).
- One of them pushes up (or opens a hole, or out of the screen, or whatever) for packages that YOU want to collect.
