At the beginning, Kat is asked to go find the gravity cat. When the cat demonstrates its powers, it lifts Kat and a couple of bystanders into the air, then flings them. Kat is flung towards a building and safely lands, while the other two get flung roughly upwards into the sky...And we never see them land in any direction or come back down. At least, in the demo.
Actually, whoever is close enough when you find said cat get's lifted. If no one is nearby, it'll just be Kat.
It still makes me wonder—if the cat flings them upwards, what happens to them? I'm sure this is Offscreen Inertia happening to me here, but for all we know, within a few hours, they'll have left Earth's atmosphere.
