Holy Invasion Of Privacy, Badman! What Did I Do To Deserve This? is a strategy/puzzle game for the PlayStation Portable. The game centers around creating mazes and monsters to help defend a demon lord from heroes seeking to capture him.
Using a limited number of “steps” and a pickaxe, the player must dig and create a maze with monsters in it to defend the demon lord from heroes. More steps are given when a stage is cleared, based on how well the player did. The “steps” have another function, however, they are also used to add levels to monsters. At first, the player must dig and create the maze while creating monsters before a hero comes to capture the demon lord. When the hero appears and is going to enter the maze, the player must take the demon lord and change his location, prefferably making him harder for the hero to find. When the hero gets into the maze, he will take random paths (if there are more than one) until he finds and captures the demon lord. The hero will fight against any monster that gets in his way.
When the hero captures the demon lord, he will go back by the same path taking the demon lord with him. It is possible to create monsters to save the demon lord during this
The ground changes with time and the amount of time changes the appearance of the blocks and the monsters that are created from that block. The death of monsters or heroes, along with some of the heroes’ actions, has varied effects on the surrounding ground.
