This is a very small 3d shooter and it is just 96kb. No images or other stuff has been included in this game, that's because it's programmed in a different way. The pc has to calculate the whole game first before playing.
Have a look for yourself:
Very impressive for only 96k. I did get stuck in a doorway once, but M+1 respawned me to an earlier room. I assume this game was just a fun exercise in C++, because it is little more than a 3D game of Pac-man (without the maze). Although, it does show a lot of talent in graphics.
