tl,dr: It looks incredible, like no other game you'll see today, and it grapples with deeply interesting themes – but it's extremely annoying to play and suffers from a serious lack of editing. There's just too much friction to become truly immersed. Still, other games can only wish their failures were this daring.
Out of curiosity - did you read the book before playing the game?
I'm asking because as I said in my comment - I really loved the game, but I do wonder if knowing the secret of Regis, The Invincible and its sister ship made it easier to play and overlook some of the mechanical problems(which in my opinion really weren't that much of a deal, I think I got lost driving the rover once but like, meh).
I didn't, no. I've read a lot of Stanislaw Lem but The Invincible never quite hit my radar. I can see how knowing the story would've made it a bit easier to get on with, though.
