A new version of Kharne (v0.0.6a) is now available (source also available here and released under the MPL). This is mainly a bugfix version superceding v0.0.6, although I've made some other additional changes.
Changes to this version are as follows:
Potions can now be drunk when confused or blind.
Some monsters can now pickup selected items from the dungeon floor.
Monster Breath Attacks are now represented graphically by a 'beam'.
Dungeon features (e.g. growths, piles of bones etc) are no longer passable by default and must be 'T'unnelled through to pass.
Added tooltips for Background Dungeon features.
Whenever the Player Character enters or leaves a Background Dungeon feature, an appropriate message is displayed in the Message Log.
Stair descriptions are now more thematically appropriate.
Changed the glyph for an open door from \ to '.
Magical items have been increased in power.
Fixed an issue with certain dungeon features not appearing whilst in steath or enraged.
Trying to drink a potion or read a scroll whilst unable to do so will no longer consume the potion or scroll.
Potions of See Invisible and Combat Mastery now have correct expiration messages.
Scrolls of Enchant Weapon will no longer enchant Shields.
Fixed an issue with not displaying the unidentified name of Potions of Might.
Potions of Might now triple the character's bonus damage, not their strength.
Potions can now be identified properly by using Scrolls of Identify.
When IDing a Scroll by using it, the Scroll Type will now be displayed in the Message Log.
Cursed items are now significantly worse in effect.
Monster Tooltips now indicate if the Monster is unaware of the Player Character.
Monster appearance messages now check for Player Character Stealth properly.
