Ghost Trick: Phantom Detective is an adventure puzzle game by Capcom and released for the Nintendo DS in 2010. It follows the story of a spirit named Sissel, who had just died, and wants to recover his lost memory. With his special ghost tricks that he received, he can manipulate certain objects and erase the deaths of certain characters who died for less than a day.
EZGames69 solves the mystery in record time.
We strongly recommend playing the game before watching the TAS, as it evidently spoils some key plot points as well as the solutions in the game.
