POWDER is a roguelike game, which is not a port of an existing roguelike. It is built around replayability and long term ergonomics, not short term learning. Author of this piece of software is Jeff Lait.

zear gave it a go for Dingux, but there are issues with the resolution (too small) and input (no button mapping). Besides that the game was playable.
