How do you recover old games?

so i was browsing my friend’s favorite lists because they have a habit of changing their display, and found he favorited an obscure decal animation game.
it’s pretty old too and holds up

i want to recover most of it but he’s terminated. is there a way to view the deleted inventories or even profiles of users?

it seems like the guy only logs on for nostalgia, atleast that api works

if only the audio privacy and termination didn’t butcher it

i’m active on the wayback machine so this is fresh lost media for me, i need advice
