Powder

POWDER is a roguelike originally developed specifically for the Game Boy Advance (GBA). It is not a port of an existing roguelike, as the controls of the GBA are very different from the traditional keyboard, and the screen imposes some additional limitations. It is built around replayability and long-term ergonomics, not short-term learning. It uses actual graphic tiles (16×16) rather than the traditional characters.

The goal is to descend into the depths of the dungeon until you reach the foul daemon known as “He who the author cannot spell consistently”, or Baezl’bub. When you have slain Baezl’bub in heroic combat, or, if Baezl’bub dies in any way, retrieve his black heart and bring it to the surface world.
