For a basic Indie game, this is a marvelous piece of work! The controls are simple and smooth; the pixelized graphics, scary flashlight system, and challenging gameplay make this a fantastic purchase.
Specifically noted is the ominous background sound, which is enhanced with the addition of headphones. The static accompanied by the slenderman scare is terrifying!
Th downside- there is no difficult setting, and the slenderman is notoriously hard to evade after the second page is found. In addition, I feel personally that the girl's voice should be removed or replaced. Other than these small issues, Slender: Last Sleep is worth the price!
