I realized that when you die, if you hit space one time to see mortem, but then hit alt+f4(or any other way you'll close window of DooMRL), all kills will be added to your character statistics, but your death won't be count there(and in "score.dat" too). It's really cheater bug, because you can raise your statistics fast and without problems(just save-load on last levels of game and die every time you load).
And one more. In mortuary, when i picked up and AA and put it on, i remained white. As i remember from previous game, AA is yellow. I had at that time Tough As Nails*3 ; Ironman*3 ; Brute*3 ; Eagle Eye*1 and a lots of red armor in backpack.
