About this game
Rex Runner GB brings the familiar running dinosaur to the Game Boy. Rex moves automatically through a scrolling desert while your score rises with distance. Cacti and flying obstacles leave you to judge when to jump, when to duck and when to stay on the ground.
Choose Start from the menu with the arrow keys and X. During a run, X is the Game Boy A button for jumping, and Down makes Rex duck. Pressing Down during a jump brings Rex down faster, as shown on the game’s Controls screen. Enter pauses and resumes play.
A collision ends the run. Press X to try again, or Z to return to the menu. Start with short, well-timed jumps and use the Controls menu to review the actions before chasing a higher score.
