Fear is one of those games I tried a long time ago, tried to play without hints, got stuck, tried again, and quit. So I walked through it just now with the hints, and it was interesting to see what the game was like.
You navigate a small house, but your fears don't let you do anything you want to do. Three objects in the game will give you flashbacks, like the game Photograph. Each of these flashbacks contains a difficult puzzle, all of which require lateral thinking.
Overall, an interesting game, but much too hard in my opinion, and not entirely compelling outside of the puzzles. However, if you do like puzzles a lot, this game is pretty fun.
