The first time I downloaded this the DMG wouldn't mount. But today I was able to download without problem, so I guess the problem was temporary. I tried the game a few times, and the play seems a bit familiar, reminding me of the "Nanosaur" game that used to be included with Macs a few years back. The "Torque Demo OSX" threw me at first, as it seems to imply that the game is still in demo mode, when in fact it appears to have accepted the serial number.
My general impression is that this is a fine game for a freebie, but I probably wouldn't purchase it.
