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:

Help menus are no longer off by one. (Patrick Don’t have one, Matt_S, Sam Spencer, Alex Marsh, Robert Barber, mattock)
Remove potential crash when zapping wand of invisibility off map.
Items are no longer revealed by hostiles searching.
Status message “Searched” when you search to make it more clear you did something by searching.
Correct lighting tests for giant mobs along with looser LOS requirements to see them.
No longer crash if a rolling boulder kills the caster and then fills a hole.
You can click-drag on display text to scroll it.
Chris Lomaka’s tiles have been updated with some nice new additional icons.
Help menus are platform specific, so GBA users should no longer be taunted with stylus help, etc.
The Akoi Meexx 10×10 and 12×12 tilesets are enabled in SDL builds. The 10×10 has had a round of manual smoothing applied to it.
Status bar on iPhone now rotates and is hidden in landscape mode.
iPhone now uses native keyboard controls.
If you start the game in a room with only secret exits, you are explicitly told that there are secret exits to search for. (Eisel Mazard)

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