Complex is the fifth level in The Keys of Krodacia. Like the name implies, it is a complex where the player has to scale this fortress for points, gems to open doors and an extra life. This is the first level that is not required to complete the game and the only one where Acid Tubs are present. Other than that, the only inhabitants here are the Patsy and the Magifly.
- There are a total of 81,400 points in the Complex. It means 37 Krodacian Sodas, 61 Blue Peppermints, 13 Chocolate Bars, 11 Sugar Cubes, 9 Burgers and 6 Strawberry Jellos (3,700 + 12,200 + 6,500 + 11,000 + 18,000 + 30,000 = 81,400). There are 33 gems and a single 1-UP.
