POWDER is a roguelike originaly developed specifically for the Gameboy 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 game goal is very simple: 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.

Release notes by nop90:

This is only an preview release, everything seems to work but the game sometime hangs ant there are a lot of thing to do to improve the GUI (like using the bottom screen adding touchscreen support and increase the resolution to a full 400×240 pixel (now it’s a gba resolution zoomed). If you want to test it, save often to avoid to lose your game if the system hangs.
