Edge Grinder

Edge Grinder is a side view scrolling horizontal shooter where the screen
scrolls constantly as you move your spacecraft around the screen blasting
waves of alien ships. As you move from left to right over one level, you must
shoot or avoid the alien ships or you lose one of three lives. Your weak point
on your craft is the centre so you are able to grind your craft along the
walls and obstacles that appear for extra points.
