Loadstar: The Legend of Tully Bodine

Loadstar is a rail-shooter concerned with shooting enemies while navigating your ship, much like Sewer Shark. You're actually on rails in this game, as you travel in a truck/train called Loadstar along a magnetic rail network covering the moon. Shifting the cursor to the edge of the screen changes to a different track when available, with incorrect turns either killing you instantly or moving you off-course from the level end.
