In Spacerunner, you'll be taken through multiple levels through different backdrops and have to jump, dive, or roll over various objects. Your character will be constantly running, so all you need to do is get used to the arrow keys. The up key is for jumping and best used to get over objects that are directly on the ground. The right arrow is for diving and is best used when you have two objects together or a space between two objects. The down button is for rolling and best when there is one object about waist to head height. The scrolling gets faster and the graphics get better each level.
