My favorite mode, "Classic", is a truly great game - very satisfying, exciting & extremely addictive. The others were less interesting to me.

The program really doesn't yet work adequately on a Mac interface. - Yes, it's clumsy and inhospitable to the Mac userworld, but not so bad that it causes crashes or requires "Force Quits" or hard restarts to ge out of it. However, it certainly does NOT deserve Duckhue's "Best of Show ... First Place as the biggest piece of crap I've ever downloaded", although it needs a LOT more work! Definitely not yet worth more than $5.00.
