Paladog is a kind of inversion of the tower defense genre. After the gods have cleansed the earth of corrupt humans, the devils strike back against Critterland with corrupt hordes of reanimated human dead. Paladog's mission is to defeat the undead armies and destroy their strongholds.
In the game, the player can cast spells through maces with mana, and use food to summon allies. The goal is the destruction of the evil stronghold, which spews undead enemies to oppose you. Defeating enemies gives experience, money, and random gear. Gaining enough experience to level allows the player to upgrade one of Paladog's abilities. Money can be used to purchase upgrades for allies or to buy gear. There are two kinds of gear: maces and rings. Maces are used to cast spells, and rings augment various things, such as experience gain or mana regeneration.
