Press arrows to move and space to use beam. Alien guide: Green = 1 point. Blue = 2 points. Gold = 10 points. Diamond = 50 points. Purple = All orange vanish. Orange = -1 life. Black = Game over. WARNING: Gold aliens sometimes make you suck things up without pressing space. Lots of gold to find, so go go go!
There are lots of other space speeders games, which you can find in my "intelligent life..." studio.
