Fire and Ice

Fire and Ice (no relation to the 1995 platformer game named Fire & Ice) is a Scramble-inspired space shooting game. You fly your ship up and down, shooting baddies with your lasers or avoiding them. Your fuel is constantly decreasing, so make sure to collect some (it appears on the ground as balloons) before you run out. Later levels add abilities to the enemies, such as shooting lasers of their own. It's a little choppy but plays decently enough for a CGA game from 1989. (Note: The game begins with a blank black screen, press any key to get past it.)

This is the same game as Fire & Ice, which has the full page.
