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.

Changes:

Leather helms will actually use the new leather helm icon. (Bunnyriffic)
Doors to special rooms will hopefully now be properly blocked so wandering monsters don’t wander through them.
Secret doors should no longer be giveaways in dark rooms by being the only lit wall.
Special overlay tile when creatures are on fire.
New special weapon, the earth hammer. (Ibson the Grey)
Creatures may teleport you to escape rather than always themselves.
Creatures will use wands of sleep to escape. (Derek S. Ray)
Creatures that are tame to someone other than yourself are described as followers rather than tame. (Derek S. Ray)
Picked up items always go to the end of your inventory rather than filling holes, hopefully making it easier to find items you just picked up. (Malte Helmert)
H’ruth is no longer impressed by you being surrounded by sleeping or paralysed enemies. (Robert Hamaker)
The charging of lightning rapiers is now proportional to the damage that would be done.
Tlosh will grant exotic armour skill. (R. Dan Henry)
Necromancer and Barbarian dress codes (R. Dan Henry)
When polyed into a grid bug you can move diagonally with the stylus, mouse, or the new Move command. (Michal Bielinski)
Flamestrike’s strength now is dependent on your favour with your current god. (Xaintrix)
Ghosts are no longer able to bypass the library’s locks.
You can make secret doors and hidden traps. (CYBER Aeon)
You can smash viewports. (Brendan)
Name generator has a hotkey so keyboard purists can use it. (Brendan)
Forgetting things no longer leaves the menu on screen.
When turning to stone or poisoned your apperance changes.
The final damage from poison is now applied before the you are cured message, leading to a less confusing apparent order of events. (Andrew Poandl)
Ibson the Grey tileset white and red dragons fixed. (Vladimir Stalin)

Note: While the highscore is kept, save games are never preserved between versions. Please wait until your current character dies before upgrading.
