mothwentbad: Nice post. I think my biggest remaining questions at the moment are these:
* How do you survive a bout of blindness? (I seem to get this mostly by walking through a door, so keeping notes on which one is which should do, unless there's some other way of getting afflicted. It's an unreasonably long duration to just tough it out, though. :( )
* How do you deal with food? Clearing a whole level is fine for exp, but the hunger meter falls really far, even on Easy. Backtracking to clear one unexplored room or two could cost a lot.
With the blindness if you clear the nearby area first before going through the trapped door you can just wait it out. It's just 30 turns each time. If you hover the pointer over the colored symbol of the trap on the door, it'll tell you what it is if you've identified it before by walking through it and having it effect you. So even if you forget what color a specific trap was the tooltip will tell you. If you haven't activated that trap yet it'll just say "trap". If you didn't notice the trap before walking through the door, and so are blinded when enemies are around because you didn't have a chance to clear the room and nearby area, there are two tactics to deal with them: one, if it is melee enemies, continue into the room one square, then move over into the corner. This only gives three squares your enemies can attack you from. They'll be hitting you, but you can figure out which square they are on easier this way and kill them. If you retreat to the corridor you can attract more enemies, and there are many more squares that they could attack you from, lowering your chances of finding and killing them. If they're ranged enemies, like robots, back out of the room a square, then a few off to the side and wait until the blindness wears off. You'll cut off the line of sight to the room so you can't be shot, and ranged enemies
usually won't come out of a room because it will give you a free attack and the AI will weigh this as not worth it. So using these two tactics based on ranged or melee enemies you can normally deal with unexpected blindness. Of course the odds may just be too stacked against you and you die. If you're in a situation like this though, where the chance of death is very high, ALWAYS use all items at your disposal. Since it is permadeath, there is no reason to save them because if you die, all of them are gone for good. If you have to, use all your healing items and grenades, etc. In most games I hoard all consumable items and usually beat the game with tons in my inventory, but with Roguelikes there's no reason to NOT use them. You just need to get good at identifying when you're actually screwed enough to need them.
Food is a little more tricky since it varies much more on the overall game and random elements. I usually don't have an issue with food, but it might be because I play Engineer, and so can open most things and get more food as loot drops. One thing I do though, is always eat it right away if it's not something I can feasibly craft to something better in the near future, and it won't put me over my limit. Food and crafting items I usually save until I'm near starving are meats, breads, scent glands, and bindings. These are all relatively easy to find and can be crafted at low biotech levels to better items. And if you didn't know, you can loot those garbage piles in the beginning level and they'll usually drop food items like pellets that give you a little bonus early on. If you're smart about exploring the map you won't have to backtrack to explore individual rooms, and exploring one room only costs a few food points. Try to keep it methodical and don't stray from the most efficient way to explore, and the only times you'll have to backtrack is when the ladder down is found early. The problem arises when the map is explored randomly and you have to go all the way across it several times. This usually happens when chasing enemies, or going after really good looking rooms that are slightly out of your "efficient" path--you'll get to it eventually.
