The first-person game tasks players with collecting notes across various maps whilst trying to avoid the Slender Man.

Slender Man received mixed reviews, with praise directed towards its atmosphere, graphics and sound design.

The player's vision automatically moves towards Slender Man when he is nearby, requiring them to "swipe and claw at [the] screen to tear free".

[2][3] Slender Rising features several customizable options, including difficulty levels, filters that obscure or change the player's perspective and four different maps.

[2] Devlin and Slide to Play's Chris Reed were more ambivalent: while he praised the atmosphere, graphics and sound design, Devlin felt that Slender Rising lacked enough originality to distinguish it from other Slender Man games in order to scare players familiar with the genre.

[2] Reed similarly praised the graphics and atmosphere, but considered the actual gameplay boring and unengaging.
