Two player snake game. Both people shoot each other to gain points and collect "food" to increase health and ammo (your body is your ammo) while avoiding any dark (less than RGB(20,20,20) ) areas. Goal is to get the most points, the game never ends, and any bitmap can be the map (drag and drop on executable)

Space invaders meets Raptor meets the third person genre. Fly through the wormhole and survive as long as you can, watch out for the motherships!
