DUMB0.13.11

DUMB is a 3D graphics engine more or less compatible with that used in id software's Doom. It plays Doom, Doom II and Heretic levels, and also allows you to create your own. A level editor for X is included. This is a work-in-progress. Requires GCC, G++ (but no class libraries), and netpbm to compile properly, and a Doom or Heretic wad to play.
