It seems like you can actually softlock the game, I got to the boss fight on the rooftop with Intern and having lift objects, and after kicking the boss out of the arena a few too many times he actually stayed on a lower out of screen platform, never coming back
Edit: Apparently YOU can also get stuck there if launched while during his antigrav attack (the zone is bottom right of the screen, havent managed to get him stuck on the left)
