I first played this game through on PlayStation, and I've now found the pc version here on gog.com. Controlls - At first, I was spectic about how the pc version would work around the important (yet missing) PS analog sticks, but I was surprised that it works very well (arrow keys for left, num pad for right, and luckily, you can easily change num2 to num5 for arrow key resemblance). The mouse provides for other interactions and gives you the choice of keys only- or arrows/mouse gameplay. Gameplay - Breathtaking immersion. The story (weirder as it gets) compliments the eerie setting (imho). The writing and timing of how the characters interact (in)directly can provide SO many different outcomes (never load unless you're game over. Every mistake provides to your story!) Challenges depends only on your reflexes and coordination to (and this is cool!): "feed you the story while you're preoccupied; keeping your eyes glued to the screen while flashing the action behind it!" You don't focus on it, but your subconsciousness picks up EVERY bit of it, giving you a much more (desirable, imo) primal kick out of the scene. Conclusion - There is no reason on this planet to not, at least, try this game.
