POWDER is a roguelike game. It is not a port of an existing roguelike. 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.

Changes:

Added a signpost in the tutorial warning of kiwis along with a kiwi to be warned of.
Familiars always have 10 HP rather than being a the mercy of a die roll.
On level up NPCs will gain a half magic level if they are magic users.
Some monsters have an advancement track. When they reach a certain threshold level they will grow into a new monster type.
Water walking creatures are now aware that they are not safe from acid so will no longer wander to their doom. (hotpoo)
Reworked how god distribute spells. This allows some more variety in non-wizard gods. Quizar will now grant spells on occasion, for example. Likewise, Pax will grant Flamestrike and Tlosh Magic Missile. (hotpoo)
Famliars will learn spells as they level up.
Track added to familiar tome.
New spells: diagnose, summon demon.
Summon Imp made cheaper.
Boosted power of Baezel’bub.
Page up and Page down can be used to quickly navigate lists, as can [R] and [L] on the GBA.
You can now Split Stacks in the inventory screen. This peels off one item and places it separate from the stack. Useful if you want to drop one or all but one of something breakable.
When you finish getting help on a spell or skill you are returned to the skill selection menu rather than to the inventory menu.
‘?’ can be used to get help on skills in the read menu as well as ‘i’.
When you finish viewing a help item, you are returned to the help list rather than the main game.
