Turborilla has released their very first title for Mac OS X, Mad
Skills Motocross (http://www.MadSkillsMotocross.com/). It’s a
sidescrolling motocross game that costs US$25.95.

Mad Skills Motocross has 40 racing tracks and 12 special challenge
tracks. It’s about racing against the computer or against friends.
Getting to the finish line in the shortest time possible is the
primary goal, while pulling off backflips, frontflips, wheelies and
more is the secondary goal.

You’ll collect achievement-like stars for tricks. You will get
power-ups that might seem silly and useless at first. But these
power-ups will be very useful once it “clicks” for you and you figure
out when and how to use them.
