Trailblazer

An action game in which you must guide a ball-shaped craft through a succession of levels. These have a patchwork-quilt type display, with holes to avoid, and squares of various colors, which affect the craft's speed, both within its power potential and into warp, as well as a control-reverser and lots of holes. You can jump and thus avoid these holes, although you have a limited number of them for each level. (mobygames.com)
