To really make the game frightening you have to be able to die. After figuring out that my character was immortal I basically just moved around with impunity. Monster hit me? Eh, who gives a shit, not going to do anything to me because I got plot armor.
If making a scary game was not the intention, then what you're left with is a game that's got rather plodding gameplay. I mean, what is fun about walking around a map trying to little glowing lights in plain view? There's no learning curve to any of the essential tasks at all... everything is idiot proof (reiterated by the fact you can't die). So, basically you just wander around aimlessly until you find what you need.
The only reason I'm giving this 2.5 stars is because I think there was potential here and it was at least engaging enough to make me complete the game.
That said, wouldn't recommend this to anyone that isn't bored.
