In this puzzler, you play as a ghost. the goal of this game is to help all the people in a room escape. if any of these characters see you however, you lose (because saving people is a thankless job.) the main gameplay mechanic of this game is possession. as a ghost, you can possess both animate and inanimate objects and move around in them. although this restricts your movement, it allows you to interact with the physical world and guide characters out of the room. here, we'll flesh out the three types of objects the player can control--the ghost, moveable characters, and inanimate objects. the player can only control one object at a time and switching forms will is required to solve most puzzles. when the ghost is possessing a character, it maintains all of its basic physical properties (height, weight, shape, etc.) however, now, the player is able to control the movement of whatever it is possessing or exert forces on it to make it move. below are descriptions of all the kinds of objects a player may possess: ## characters ### the ghost the ghost moves wherever the player touches on the screen. the only thing that limits the ghosts movement is a barrier (i.e. a wall or a platform.) if there is a barrier between where the player touches and the ghost, the ghost stops at the point where the barrier intersects the straight line between the touch and its original location. the ghost is not effected by gravity or any other physical object other then barriers. also, the ghost sprite is not present on the screen in any form when it is inhabiting another character. ### moveable characters moveable characters constitute any character that can move to new locations on the screen, i.e. has locomotion. moveable characters do not have to be constantly moving and they may not move at all--one may simply stay stationary. the ghost can possess any moveable character and can then move with the ability of that character. while all the physical properties and movement limitations of moveable characters remain unchanged upon possession, a number of properties differ.
