Same, but simpler B&W version of the Dirt Bike racing game. Create and save your own tracks. A very fun simple physics 2D racer.
Althought this game works with Basilisk and SheepShaver up to Mac OS 9, its best play is Mini vMac.
thanks for the update! I designed some wicked tracks for this - but overall, I enjoy Line Rider (flash) a lot more.
