The killer behind the scene

You are never alone. You find yourself stuck in a house with your nine buddies, and with just your luck, one of them is a killer, content with picking each of you off day by day. Every time the murderer strikes, you have a chance to decide who is it. Only when the murderer is revealed and killed shall the door open to freedom. There are different roles assigned to different people that will help along the way. Enter now, if you dare, and hear the door shut behind you. This is based on the roblox game Flicker! This is also my first book, so any feedback, whether positive or negative is welcomed with open arms!
