Horrible Performance!!!

I have a 2010 MacBook Pro with 2.0 Ghz processor, 8 Mb RAM, ample HD space, and whatever the standard graphic card is for 2010 MacBooks... And, game hangs every second (literally) so I have a horribly slowed-down stop-motion on the screen. Although my system is not the newest out there, but it is still much higher than the minimum specs advertised at Mac Store. I think this is a rip off!!!
