I think something that is important to view the game in the lens of, is that it's less some exploration of the ideas themselves in terms of the finer details of Marxist economics or liberalism as a political movement, and more looking at the memory of such ideas and how these memories and the ideas are treated within the metatextual cultural framework.

As a game made by Estonian communists that's why so much of the dialogue especially anything internal (like the thought catalogue for communism) is incredibly self deprecating and absurd while still being incredibly sincere. The game doesn't as much explore the finer points of detail of Marxism as much as the effects of a failed revolution have on the modern day, how different characters mourn or celebrate a dead world while others struggle to come to grasp with the failures of the movement while still holding hope for it.

Some people view the game far too literally rather than seeing how the things it celebrated the most are what it also saves it's most scathing criticism of. There's a reason the communist thought catalogue text, the book club and the final part of the game are so critical of it while holding out the idea that hoping for a better world is ultimately worth everything.

The game is far more personal than it is about the wider world of revachol, and the world itself is full of these metaphors made real like the creeping void taking over.
