So basically go inside of the project and put your character in the image slot and describe them. (THE CHARACTER DOESN'T NEED TO BE HUMANOID) Then put the name of the character in the name section. Lastly, give a few voice lines for the character so I have reference. (MAKE SURE IT'S NOT TOO BASIC, I WANNA SEE OC'S AND STUFF LIKE THAT.)
DO NOT, I repeat, DO NOT use the sample character as a base for your character. If you do the same thing that happened with ready set clash, I'm just straight up ignoring it. Also, make it scary, it's for a horror game of course.
