Iriegas for MSX is a 3D maze escape type game. You hear a constant humming sound as you play, and it increases in speed as you get closer to something, an enemy, I believe, but I haven't been able to ascertain that it couldn't be something else. The sun is visible and it can get dark. There are night-vision goggles in the first level (don't know if they are available elsewhere or not). You can escape the maze and go on to the next.
