Project: SLENDER is a puzzle-adventure game. You have to run away from a creature that wants to catch you. Your only hope to survive is to collect the pages that will allow you to open the door.

You can open the door by collecting the required pages. To do that, you need to go through the different passages that you will find. Each passage will have different obstacles that you need to overcome to reach the exit.

You can also find different items in the game that will help you. These items include torches, lanterns, shovels, axes, and pickaxes. With the help of these items, you can find the way to the exit.

You can also find a trap in the game. If you get caught by the trap, you will be locked in the room and you will have to start the game again from the beginning.
