There are also now links to the Slender Man Mythos Forums and some popular web series based on the Mythos such as the 'Marble Hornets' and the 'TribeTwelve'. From version 0.9.7 on, there is an ambiance during the menu screen, as well as portions of the eight pages being shown.

It remained this way until version 0.9.3 (the third update), and the player now has the option to either try again or to quit.

Originally, when the player would be caught by the Slender Man, the game would quit and return to the desktop. The game was first released in version 0.9.0 as Slender. The '$20 Mode' has been absent since version 0.9.7 The accompanying readme advises 'One game mode removed - it was only a matter of time as it contained copyrighted material', referring to the Browz track that's used in that mode. The creepy sounds and page collector have been removed, there are static bars on the edges, and the ending is slightly different. There is also an 'MH (Marble Hornets) Mode', viewing the gameplay as a 'Marble Hornets' entry. This is the only version in which the Player selects these modes in the 'Options' portion of the menu screen, and this is also the only version in which two hidden modes can be played at the same time ('Daytime Mode' and '$20 Mode'). This is a reference to a fan-originated meme about Slender Man, stating that if a person gives Slender Man $20, he will leave the person alone. In this mode, the gameplay is the same as 'Normal Mode', except that if the player sees Slender Man a song called '20 Dollars' by Americanrap artist Ron Browz starts playing. After the credits roll, the player will have unlocked '$20 Mode'. If the player beats 'Daytime Mode' the ending will be the same as before, only the player wakes up at night. 'Daytime Mode' is simply during the day and without a flashlight. After waking up, the player can walk around in the daytime for a few seconds before the credits roll. To unlock this mode, the player must beat the game on 'Normal', in which the ending shows the player's character awakens in the daytime after collecting all eight pages and being caught by Slender Man. In Version 0.9.4 there is a 'Daytime Mode' that can be unlocked. The game over screen shows Slender Man's face up close and blinking static pulses. A game over occurs when either the player has taken too long to find a note, the player stares at Slender Man for too long, or if Slender Man comes into contact with the player, which will turn them around and end the game. 'Sprinting' allows the player to move faster than 'jogging' does, but will also decrease the maximum stamina available for 'jogging' and 'sprinting'. This then allows the ability to 'sprint' to become available to the player. Slender Man will occasionally appear in the player's field of vision, accompanied by a loud slamming noise and/or static on the screen. The player's character has the ability to 'jog', which will eventually tire out the player and make them wheeze if forced to go on for too long, causing slower walking as well. The player is equipped with only a flashlight to see through the dark (its battery life is limited and will eventually shut down permanently if left on for an extended period of time). Slender Man moves by teleporting, creeping around the player, but only from a certain distance. As the player collects pages, the fog in the forest grows thicker, and Slender Man appears closer to the player's character, though the character's sprinting speed slowly increases as well. The player's objective is to collect all eight notes located in various areas of the forest while avoiding the Slender Man. Slender: The Eight Pages is set in the middle of a forest during the middle of the night, and is played from a first person perspective.
