This is pretty much Frogger with an armadillo instead of a frog.  It's a great version though that is seriously addictive.  I was a little confused at first but once I got the hang of it the game turned out to be a lot of fun. 

Your ultimate goal is to get from one side of the road to the other and into the cave on the other side.  Be sure and look at which cave is open for you!
