People not social distancing in game? (5,8)
I believe the answer is:
space invaders
This clue is a double definition.
'people not social distancing' is the first definition.
(people invading others' personal space)
'game?' is the second definition.
(Space Invaders is a video game)
'in' is the link.
(Other definitions for space invaders that I've seen before include "Early computer game" , "Early arcade game -- aliens?" , "Early electronic game" , "They'll leave you little room" .)
