Cyber Snake

Cyber Snake is a "snake" game where you have to collect all the diamonds in each level before the time runs out. Every time you eat a diamond the snake grows. If you crash into a wall or into your own tail you die. Every level contains a variety of other devices, most of them potentially lethal. At the end of each level you get bonus points for remaining time and you also get a password so that you don't have to start from the beginning next time you play. Among the devices you encounter in the game are doors (which requires keys), mushrooms (which reverses the controls a short time) and bombs (explodes when activated).
