You should explore the idea of having cutscenes of our main character getting killed by the monsters like in some other horror games, but that's obviously your choice to make and I will respect your choices.
I think the official names are in a copyright grey area, so they probably wanted to avoid the possibility of getting sued. The same thing with Millie looking slightly different from Minnie in the original cartoon. Technically, Minnie is not in the public domain, yet.
