Another interesting detail is that some decision results are indeed random. You have to repeat Russian Roulette multiple times to get both results. Common for RPGs, not so common for visual novellas and puzzle games.
At some point they introduce an alien machine that can teleport people to the past. The caveat is that it works like a fax. It creates a copy of you. But you also stay stuck in the place you tried to escape from. Reminds of the Soma game.
The midgame is slow. At first, you solve all those escape rooms and make decisions and have fun. But then the game forces you to take all the OTHER decisions. Some of them quite stupid, like deliberately losing at Monty Hall game. But you need to see all the deaths in order to progress.
But finally we get to what’s we’re all here for, the endgame mindfuck revelations. The game starts with a story about a boy that died waiting for a surgery, because his surgeon got into an accident. Turns out Q is that boy. Well, not exactly. Q is controlled by a quantum computer, and there are a lot of Q’s doing menial tasks like getting rid of the bodies, but Q was implanted with consciousness of that boy. He’s given a choice of creating a copy of himself in a virtual world living a happy life and continuing his life as a drone, or to completely erase himself. Again, resembles Soma a lot.
