The 1st video game I ever played was a DOS game somewhere around 1990. it was a 2-D game where you piloted a missile-shaped ship through space. You would periodically recharge (slowly) at white dwarf stars, or more quickly at red (actually purple) giant stars (which always had a skull & crossbones in the center). You would also periodically encounter (& subsequently fight) ships from 2 alien species: Humanoid snakes, & humanoid 3-eyed tigers.
That's all I remember. I'd love to play it again for nostalgia's sake, but I can't remember the name :'( Does this ring any bells for anyone?
