Parsec Productions received more fame for its release of Slender, a first-person horror game where you play a character who is searching for information about the Slender Man. Slenderman, which actually predates Slender, gives you more horror and story about the character who slowly causes you to lose sanity in the Slender computer game.
However, the aim of Slenderman is quite different, and this game finds players transported to a forest where you're running not only from the man himself but from slender children as well. Talk about upping the creep factor. Your ultimate goal is to kill him, not find out about his origins, which might be more satisfying for some players.
Your travels bring you to items and weapons, like the gun that is capable of killing slender creatures. The objects you find do make the game slightly more interesting. As a keyboard-based game, this can become frustrating. There's a lot of key mashing, because you must repeatedly shoot at your foes to actually kill them. If you're too slow, your life is forfeit. There's a certain Mountain Dew-fueled motivation to this style of game play, but it's definitely not for everyone. However, the keyboard controls are sure to satisfy those who loving playing games in front of their monitors in the dark of night.
Similarly, we're not head over heels for the graphics. This game is older than Slender, and you can tell. The graphics lack some of the true terror and painstaking details that newer games, especially those on consoles, have brought to the genre. In fact, the monotonous indoor environment might actually detract from the fear factor of Slenderman, which may mean that this game doesn't quench the thirst of the hardcore horror fans. Aficionados of the story might find this game enjoyable enough, regardless.
