Bugs was the first winner of Color Computer Magazines programming contest. It's authors later did commercial games for other companies, including Diecom Products. They also did a sequel called Bugs II that was sold commercially later.
This game mixes arcade and adventure elements. It features a very large maze, with monsters to shoot, but also you have to find keys, missiles, etc. to open doors, etc. Controls are through the keyboard only, and there are dozens of screens. Also, you can only carry one item at a time, so if you find that you have the wrong key to open a door, you must exchange that key for a different one to try again.
These two programmers teamed up with Dave Dies to create Gates of Delirium, an Ultima III style game for the Coco 1/2, a few years later.
