Neon Corridor has agreed to compose music for HyperRogue, under the Creative Commons BY-NC-ND 3.0 licence. Is this OK for Debian?
I have also (hopefully) improved some things, taking Adam's comments into account.
Regarding the dead orbs: the description for Living Caves explains how items work, and dead orbs work like other items, so I think there is no need to mention that dead orbs can be used for digging in the Living Caves. For the Alchemist Lab, I have changed the description and the dead orb behavior, so that the same holds in this case too. So I think that the text about uselessness can remain as is. (As for the games which lie that something is useless while it is not, the gods in ADOM reward you greatly if you find a use for an item called "potion of uselessness"...)
Regarding exploits: mentioned ways to get large scores are hopefully fixed, probably there are still some ways to get large scores, but Cocytus now works reasonably well and thus it should be OK, and for challenges or whatever, a special rule could be added that you cannot stay in one place too long.
If you want to look for more exploits, the current prerelease is at
http://roguetemple.com/z/hyperrogue-40b.zip (I am waiting for the complete soundtrack before publishing this officially on the website)
The full changelog:
* music support added
* Cocytus works now (but is still available only via cheating or by getting an insane score)
* Fixed the Crossroads description (there are no longer Crossroad Rangers and big holes in the ground)
*
if you collect a lot of items in a single land, this increases the
spawning rate of wandering monsters in all lands, so you are no longer
relatively safe by walking at the edge
* the cheat mode has been extended (press F2 F4 to start cheating, then press shift+letter for various effects)
* when used on a location containing both an item and a monster, context help now shows information about the monster
* pressing F1 or right clicking while looking at the context help now displays the general help screen
* improved the general help screen
*
improved the handling of non-qwerty keyboards (movement is done
according to the QWERTY layout as previously, but other menus take the
layout into account correctly)
* Ivies have been greatly improved: they shrink if an active branch sees no good move (except at the root), they are now active as long as there is at least one segment in view, and they no longer go to the Alchemist Lab (as this caused bugs). Also, if you cut an active Ivy just after root or another branching point, it immediately regrows and spins (previously it regrew without spinning at the root, and caused bugs at other branching points)
* Worms are now active as long as there is at least one segment in view, they now destroy walls and thumpers around them when they explode (so if you find a good place for killing worms, it is hard to use it more than once), and worms and tentacles can go to other lands now, except Motion and Alchemist (but worms produce spice on explosion only in the Desert)
* Alchemist Lab: the description is more detailed now, killing lots of slimes no longer degenerates the Alchemist's Lab into pure treasure, slime beasts now destroy items around them when killed, and dead orbs no longer cause the slime to spill
* Living Caves: Foreign monsters and objects affect the Living Caves now, and cave trolls now destroy items around them when killed
* Graveyard: killing graveyard monsters slowly increases the initial monster rate in the graveyard (so grinding for Dead Orbs is harder), and necromancers can go outside the Graveyard now
