About Dungeon Dev
Dungeon Dev is about designing a dungeon for heroes to clear, while secretly working for the Demon Lord. After making a deal with the human king, the Demon Lord tasks you with building a dungeon where invading heroes emerge victorious and satisfied.
Design the dungeon
As the dungeon developer in the Demon Lord’s castle, you place monsters and traps to shape each run. Simply letting the heroes win is not enough: you must meet expectations based on their roles, including Tank, Damage Dealer and Healer, while keeping the secret deal hidden.
Face different heroes
You design dungeons for a range of groups, from the human kingdom’s Royal Knights and wild creatures invading the dungeon to ragtag heroes, noblemen’s private soldiers and veteran warriors. As you encounter these heroes and other obstacles, you must judge how to build a dungeon that satisfies each group while maintaining the right difficulty. The design challenge draws on the process of a game developer creating levels.
