Gogo the Ghost is love sick. Some evil ghoul has imprisoned his beloved princess in the castle. Your task is simple: guide Gogo to the princess so they can both live happily ever after. The cassette inlay informs you that she is locked in room 150, so I would take a packed lunch as you could be in the castle for quite a while.
Each room Gogo enters has a number, and some also have names. At the start you are asked for a password, and entering a room name enables you to commence from that point.
Upon entering a new room Gogo acquires sufficient power to allow him to become invisible for a few seconds. This enables him to pass through any of the phantoms which guard each room. Gogo is made invisible by pressing the joystick fire button. However, pressing the button a fraction too soon causes Gogo to reappear in mid phantom and "FJUP!" no more Gogo. According to' Firebird, "FJUP!" is Swedish for ,"ZAP!" - who says games aren't educational.
Apart from the phantoms you will also find a variety of useful objects scattered around the rooms. Their purpose isn't known until Gogo picks them up. At this point one of six symbols at the base of the screen will be illuminated. The symbols represent life, power, time, and differing numbers of bonus points.
The graphics are nothing spectacular but this didn't detract from the playability of the game. At a cost of £2.50 the game represents excellent value for money.
