CD-Man was published by Creative Dimensions in 1989. It is the first game I saw that uses high resolution 16-color 640x350 EGA mode, which give CD-Man the sharpest graphics among all other games around that time.
CD-Man gameplay resembles closely with Pac-Man, but comes with superbly done graphics and some extras. Like Pac-Man, we control a ball shape creature to eat all small dots on the screen. There are a few monsters hanging around, we can either avoid them, or eat them after we get the power ups scattered around the screen.
The few extras in CD-Man is tunnel that allow us to jump from one location to another location, getting key to unlock special area, some fruits and foods that appear from time to time for us to get extra points.
CD-Man is still a fun game to play even until today. You can get CD-Man here.
