About OPEN DOOR
Secondly, the scrimmers (yes they are present, but they are not so much)..
"This is my first indie horror project, the script and concept of which has been reworked several times, inspired by many classic games, drawing ideas from them. I'm not good at animations, but if many people like this project, I'll release the next game with better quality with all the cut scenes and full voice acting, in many languages." Spoiler - the game will be about summer camp.
