The game is basically a one-puzzle game. Once you've figured out what's going on, getting to the end is just applying that newly-found logic to your actions. I didn't figure it out and went for the hints which basically spoiled the whole game for me. There's no-one else to blame but myself, but I wish there would have been some warning in the hints. So stay clear from the hints as long as you can so that you won't make the same mistake.
