Rematch

I'm the person who wrote the true and proper walkthrough. I solved it on my own, though it took a couple hours.

Some people have mentioned that the puzzle seems to fight against the story. Nothing could be further from the truth.

The game is very good at making you, the player, go through what the character would be feeling, if this event was real for them. The horror at the accident, the despair that there seems to be no way to save you, Nick and Ines. The frustration at the trap you have found yourself in, the eventual detachment required to actually work out the solution, and the great satisfaction when you finally manage to break the cycle.

If you haven't played it, do so. I highly recommend not reading the walkthrough. The puzzle is 100% solvable with observation and exploration. (Spoiler - click to show)First you must escape the trap of thinking all you need to know is visible before you type your first command. Having done that, you may then escape the actual trap in the game.
