In this game, you must avoid the various types of shapes while trying to use your shot to bump these shapes into the four fangs of death on the 4 sides of the playing area. You cannot move outside the red-lined area. Shapes, when they initially spawn also cannot move outside this area. After they get shot, they turn purple and can leave the red-lined area, bump into the fangs of death, and die. The angle you shoot them from will effect how they move afterwards so auto-fire is not recommended.
