Slender - Vexation.
Slender Vexation is my 2nd game i created in Unity3D. It has creepy environment, scary sounds, shocking moments and a slenderman with AI :D. I made this game in 4 days and i will update it as soon as i can. Vexation is just like alle the other slenders - running around collecting papers :D.
