Super Hang-On

In Super Hang-On you race a motorcycle around the world, completing each section of track within a time limit. There are other bikes on the road, but beating this is not important, so they can be thought of as moving obstacles. Each continent is a different difficulty level: Africa is beginner, Asia is junior, the Americas are senior, and Europe is expert. This is a very simple and straightforward game, viewed from behind the bike in 2D (so the screen does not tilt with the bike).
