Overview
Bubble Ghost is an action video game originally created by Christophe Andréani for the Atari ST and published by ERE Informatique in 1987. The player controls a ghost who by blowing guides a floating bubble throughout a number of halls in a haunted house, while avoiding obstacles that can make the bubble pop.
Gameplay
The objective is to guide a bubble throughout a number of halls in a haunted house. If the bubble hits any walls or obstacles, then it will pop and the player loses a life. Obstacles include lit candles, electricity and fans. These can be all controlled by the ghost, who can wander around the level freely and blow at things - such as the bubble to add speed, the candle to put out the flame, or switches to turn them on or off.
The ghost is controlled using the mouse. A press on the left button of the mouse makes the ghost rotate to the left. A press on the right button of the mouse makes the ghost rotate to the right. A press on a keyboard key (Shift) makes the ghost blow.
The game is made of 35 halls (levels). Each time the player makes the bubble exit a hall, he wins 1000 points + left bonus. Action on animation may add 5000 points to the player. The bonus is re-initialized at every new hall. A new bubble is added to the player account each time the bubble exits towards the top of the hall.
