You begin your adventure on the ground floor. To get from one floor to another, you must use the staircases. But you could find yourself taking a quick trip to a lower floor via a trapdoor. There are 11 of these around the castle and, although you may end up a bit bruised if you take a trip through one, the trapdoors generally lead you directly to the floor below. There are doors which lead you from one room to another. These will open from time to time to allow you to go through them. However, if you come across a colored door - red, blue, green or yellow - you will need to have a key of the corresponding color in order to get through them. These keys are of course hidden in the many rooms of the castle. You can only carry three items at a time and, since there are four colored keys, three parts of the Golden Key and various other objects dotted around the castle, you have to do a bit of forward thinking. The colored doors will remain open once you have found the keys and unlocked them, so it's better to go through the castle, opening as many doors as you can and then drop one of the colored keys.

The 150 rooms of the castle include the 'Atic' and the caverns, which contain countless rooms. Within the many rooms you will find furniture, food, drinks, objects, ghosts, ghouls, mummies, and other monsters. You have to eat and drink, so you have to do that sparingly so as not to deplete your food supply. In addition to finding the right colored keys for the right doors, puzzle elements also include manipulating objects you find to your advantage. With bright VGA graphics and a faithful rendition of the original, The Burps finally brings the fun of Atic Atac to the PC and provides proof of why Ultimate Play The Game is hailed as one of the pioneers in action/adventure genre. Two thumbs up!
