Until Time Runs Out

You are placed on a ship with nine suspicious characters.
One by one, the people on the ship start to die.
The goal is simple. Catch the killer before everyone gets killed.
But can you even survive to gather enough clues? Be aware, it is possible to die. Surviving is easy, but the riddle won't be solved until the killer is caught. Everything might not make sense, until the killer reveals the whole story.
