There are games with a Communist background. Recently there was a point and click called Irony Curtain: from Matryochka with Love. It was okay, a bit too much of a "Guybrush Threepwood in the Warsaw Pact" kinda vibe for my taste, a bit too derivative of old games. But it had interesting depictions of early Bolshevik rule with a humorous flavour, that can inspire you.
There's also the classic "KGB" game by Cryo, the ambiance was much darker but it was not devoid of humour as well.
These can inspire you a bit maybe?
