The Krupuk Adventure is a pretty weird game that will give you a three dimensional environment to explore in order to shoot down some special monsters that are called Krupuks. This environment in which you find yourself is a maze and you will have to escape it as you shoot down the monsters.
The krupuks are also a sort of crackers and you will have to retrieve a bag containing them, but the krupuk monsters will not give it too easy so you should expect a harsh opposition. However, the reward is great, as the krupuk crackers are the most delicious.
