I have played this a few times, and may play it once again once it is completed. Probably not before and there is a reason. Through out the game I have noticed that if you do not stay within he point system parts of the game breaks. The cameras do not work, hence you can not move forward in the game, or because of a different choice you can not progress in the game (Without a end of path/Game Over marker). While the game may not be exatly linear, the way the point system is defined, it makes it hareder to follow some of the paths that a player may wish to follow. I wish you luck, and once I see a completed on this game, I will probably play it again.
