Known Bugs              : Plenty if you use the doom engine. You
                          will have to use the Boom engine if you
                          want to play level 3. Even then you can
                          sometimes get segmentation violation.
================================================================
* Instructions *

1. Unzip the files into the doom2 directory
2. Type boom -file agony.wad
3. When you are playing dont forget to use F5 to set the BOOM
   info panel and F11 to set the gamma correction.

================================================================
Textures: Mostly Doom1/2, Quake and Heretic textures recoloured and
recontrasted in paintshop-pro. I made a few textures myself. The sky is
my own. The discerning punter will notice the Southern Cross in the
sky. Spot the Aussie. The dragon I pulled off a dungeons and dragons
website. These are great sources of graphics.

Sounds: Some quake sounds, the heretic teleport sound, ambient thunder.
The Cacodemon screech is an eagle, slightly treated in wave studio,

Music: Title : Twilight zone
       Level 1: X-files
       Level 2: from Batman Cartoon Maker.
       Level 3: from Memento Mori

Special effect: Instantly lowering invisible platforms. This is used to
  (1) make monsters appear from nowhere
  (2) make objects appear where there were none
  (3) make walls become instantly passable when pushed
  (4) make switches appear from nowher

Lighting: The levels get darker as you go, to give the impression of
          time passing and the sun going down.

Do whatever the hell you like with this. Curse it. Corrupt it.
Re-release it with bugs and say Chris Lloyd did it. I don't care.
Truly.

Other wads by me:
insanity - INSANITY. The first wad I uploaded. It has some flaws but
           it does feature the shrink ray, later put into Hotel Hell.
     sh5 - SLAUGHTER HOUSE 5 (a sci-fi book by Kurt Vonnegut before he
           became `serious'). Six levels but they are not that great.
helhotel - HELL HOTEL. Only 1 level but now with its fourth release it is
           almost flawless and a pretty excellent level. The highlight
           of the level is a shrink ray! Check it out!
hongkong - HONGKONG HANDOVER CEREMONY. One big level. Lots of new
           textures and sounds.
deliver  - DELIVERANCE. Three levels with lots of new textures and sounds.
